Only 1 left in stock - order soon. The battered surface of Mercury. The bright streaks are called "crater rays." It is smaller than any other planet. Most of Mercury's surface would appear greyish-brown to the human eye. The Moon and Mercury experience wide variations in surface temperature because they are lacking the moderating influence of an atmosphere. Mercury is far denser, however, having a metallic core that takes up about 61 percent of its volume (compared with 4 percent for the Moon and 16 percent for Earth). Mercury has the widest variation in surface temperatures between night and day of any planet in the solar system. The eight planets in our solar system are, in order from the sun: Mercury, Venus, Earth, … It is the closest planet to the Sun, but it’s actually not the hottest. I was constructed of Pyrex, and sealed into one piece. Mercury is the smallest planet in our solar system. The tremendous amount of energy that is released in such an impact digs a big hole in the ground, and also crushes a huge amount of rock under the point of impact. Do we know the temperature at any depth, except the surface? From our perspective on Earth, Mercury looked like a tiny black dot gliding across the Sun’s face.This only happens about 13 times a century. But when Mercury is moving fastest in its elliptical orbit around the Sun (and it is closest to the Sun), each rotation is not accompanied by a sunrise and sunset like it is on most other planets. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days. Surface temperatures drop to about 90 K (−300 °F, −180 °C) during Mercury’s long nights before sunrise. There is evidence that it is partly molten, or liquid. Mercury appears to have a solid silicate crust and mantle overlying a solid, iron sulfide outer core layer, a deeper liquid core layer, and a solid inner core. Some of this crushed material is thrown far from the crater and then falls to the surface, forming the rays. The next full Moon will be on Sunday afternoon, October 13, 2019, The Moon will appear full for about three days centered on this time, from Saturday morning to Tuesday morning.
