Is 4.5 times mass of Sun and 37.5 times radius of Sun.It is a cephied variable.! Our sun is a star, but it is not big enough to explode in a supernova, it will simply cast out its outer layers and implode. Image: Wikipedia The image shows Antares’ tumultuous surface and reveals unexpected turbulence in its atmosphere, hinting at some mysterious process that is churning away violently inside the stellar mass, according to scientists. Our sun is alot smaller than other suns. But to compare the Sun to other stars, you'll need to ask about a specific star. Truly, those stars are enormous. More specifically, our Sun is in a spiral arm called the Orion Spur that extends outward from the Sagittarius arm. Compared to other stars, our Sun is very, very small. Recently researchers have used a network of radio telescopes scattered around our planet to form a virtual telescope which can cover 10,000 kilometers in diameter. It is thought to weigh about 4 solar masses.. From there, the Sun orbits the center of the Milky Way Galaxy, bringing the planets, asteroids, comets and other objects along with it. A yellowish-white subgiant nominally creeps at 3-4 times the sun's diamteter. It contains 99.86% of all of the mass of the entire Solar System. It is 1,287,000 times bigger than a solitary Earth. The size of Earth compared to other planets and stars: this photo of the red supergiant Antares is the best ever captured of a star other than our Sun. It's just one sun surrounded by planets, asteroids, comets, and dwarf planets. And Sirius is dwarfed by Pollux, which is eight times the radius of the sun. "Compared to the entire lifespan of the Sun, 9,000 years is like the blink of an eye," said astrophysicist Timo Reinhold of the Max Planck Institute for Solar System Research (MPS) in Germany. Suns with friends. "Our sun is a weirdly 'quiet' star — and that's lucky for all of us". How big is the sun size of betelgeuse universe today image of a star that s not the sun nasa e place Size And M Of Stars Plas The Heavens DeclareIs Betelgeuse Ready To Explode Farmers AlmanacHow Does Our Sun Pare With Other Stars Nasa E PlaceIs Our Sun S Size Average In The Universe… Read More » Ok, so compared to the rest of our solar system the Sun is incredibly massive – almost incomprehensibly so. Located 26,000 light-years from the Sun, our galaxy’s central black hole, Sagittarius A*, has a radius about 17 times that of the Sun, meaning that it would sit well within Mercury’s orbit. Our Solar System is called the Milky Way; it is a spiral galaxy and the black hole in the center is called Sagittarius A*. Our Galaxy’s black hole. It is in the constellation of Ursa minor.Actually it is a triple star system but we consider the brightest polaris A. It also is fairly small in comparison with other big stars. It's because this discovery about the Sun could cause those who think about the Drake equation to change the number of terms. Our star, the Sun, is a small star in comparsion to some other stars, it is not as hot as the big ones either.There are stars that are thousands, possibly millions the size of the Sun. Supermassive black hole found to be 40 billion times bigger than the Sun. A white subgiant normally is around 5-6 times solar. Sagittarius A or Sgr A is a complex radio source at the center of the Milky Way which contains a supermassive black hole.It is located in the constellation Sagittarius, and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.. For comparison, the surface of our own Sun is a mere 5,700 K, so if a blue supergiant replaced our Sun, all life would be scorched from the surface of the Earth. UY Scuti is just plain big, with a radius 1,700 times that of our sun Left to right: a red dwarf, the Sun, a blue dwarf, and R136a1. To put it simply, the Sun is as big as more than 1 million Earth masses put together. The supermassive black hole at the center of the Milky Way, Sagittarius A*, is 4.3 million solar masses. Comparative planetary and stellar sizes. "After all, our star is almost 4.6 billion years old. The Sun is 864,400 miles (1,391,000 kilometers) across. More than one million planet Earths could fit inside our Sun, but compared to the monumental masses we find in the rest of the galaxy, our Sun is somewhere in the bottom half in terms of size. We have also seen stars that are just one tenth the size of our sun. ... but very big when compared to smaller ones and to the Earth. A blue subgiant can be around 7-12 times the sun's radius. Its stellar classification puts it at a Type ‘G’, also known as a yellow dwarf, which is about 15 times smaller and 60 times less heavy than an average Type ‘O’, commonly called a blue supergiant. In terms of size, however, the sun has a diameter of about 864,000 miles, nearly 110 … We have found stars that are 100 times bigger in diameter than our sun. At the centre of our own Galaxy there is a supermassive black hole called Sagittarius a*. Who knows how many stars are in the universe – we still can’t see its limit if there is one. This region is known the be the home of a supermassive black hole with millions of times the mass of our own Sun. It is estimated to be about 2,100 times larger than our sun. Sagittarius Dates: November 22 to December 21 Symbol: The Centaur / Archer Mode + Element: Mutable Fire Ruling Planet: Jupiter House: Ninth Mantra: I See Body Parts: Hips, Thighs, & Liver Colors: Maroon & Navy blue Tarot Card: Temperance Sagittarius Traits & Overview. Our sun is one of billions in the entire universe. Polaris is the nearest star to earths north pole direction. Our sun is not as hot either, because the more whitish it is the younger it is and that also measures how hot it is too. First, we'll look at the distance to the Sun; then we'll discuss the size of our neighborhood star as compared to our … They have measured the orbit of a star that comes within 17 light-hours of the object in the core of our Galaxy, which is a distance that is only a few times larger than the orbit of Pluto around the Sun. Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Compared to Earth, the Sun is enormous! It is Alpha of Ursa minor.aslo known as north star. Sirius, the brightest star in the night sky, is twice as massive as the sun and 25 times more luminous. Apart from the spiral shape, galaxies can also be elliptical or irregular in form. How Big is the Sun Compared to the Earth? Let's go to the dead ones. The Sun has a diameter of 1,392,000 km (865,000 miles) while the Earth’s diameter is only 12,742 km (7,918 miles). How big are we here on Earth when compared to other planets, the sun, and some of the other stars? Many other solar systems have multiple suns, while ours just has one. But these black holes are nothing compared to supermassive black holes, like Sagittarius A*, which lives at the center of our Milky Way galaxy. After all, it has a diameter of approximately 864,400 miles (1,391,000km), which is 109 times the diameter of the Earth. The largest known star that we have discovered is VY Canis Majoris; it's located in the constellation Canis Majoris. It covers a region about 14.6 million miles in diameter. That's pretty big. Sagittarius, the ninth sign of the zodiac, is the home of the wanderers of the zodiac. If you look at the size of our Sun, compared to the planets in the solar system, you’d be forgiven for thinking that it’s a tad on the large side. This staggering image shows how our sun - which is so big it accounts for 99.86% of the mass in the solar system - would look next to the biggest star in the universe. Different types of black holes have very different masses. read more It may be the biggest thing in this neighborhood, but the sun is just average compared to other stars. Stellar-mass black holes are typically in the range of 10 to 100 solar masses, while the supermassive black holes at the centers of galaxies can be millions or billions of solar masses. At the very heart of the Milky Way is a region known as Sagittarius A. An orange subgiant can be a little over twice the sun's diameter. The Sun, and everything that orbits it, is located in the Milky Way galaxy. Discovery Channel shows Earth, compared to the Sun, and then to a few other massive stars in our own Milky Way. The black hole is 10,000 times larger than the one thought to be in our own Milky Way galaxy. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. Using the highest resolution IR cameras available, astronomers have repeatedly observed the stars orbiting around Sgr A*. It's so big that if you traveled at the speed of light, it would take 8 hours to go around it. Betelgeuse , a red giant, is about 700 times bigger than the sun and about 14,000 times brighter. I just received an email that included the following pictures, circulating anonymously around the Web universe. The Sun is so big that more than 1,300,000 planets the size of Earth can easily fit inside it. Galaxies gather in groups, clusters and super-clusters and there are billions of Galaxies in the Universe. Our sun is a little unusual because it doesn't have any friends. We begin our exploration of the Sun, which is the main source of energy for Earth's climate system, with a feeble attempt to comprehend the size scale of the Sun as compared to Earth. It's located about 5,000 light years from earth. Let’s compare the mass of our sun to a few other stars in the galaxy: Today, we know that the sun is about 92.96 millions miles from Earth, and while the distance between our planet and the sun is growing, we are gaining less than an inch of distance every year. In fact, our sun is classified as a G2 dwarf star. The scale of the universe is almost beyond our imagination. A white dwarf is around 1/100th of the sun's diameter. However, it is just one of 100 billion stars in the Milky Way. [enter image source here]!
