3. What is the greatest moon in the Solar System?
4. Which moons are much bigger than some planets?
5. What do scientists think of the creation of the Moon?
6. What does the lack of atmosphere mean to the Moon?
7. How many moons are there in the Solar System?
A. The dark side of the moon is a myth. In reality both sides of the Moon see the same amount of sunlight however only one face of the Moon is ever seen from Earth. This is because the Moon rotates around on its own axis in exactly the same time it takes to orbit the Earth, meaning the same side is always facing the Earth. The side facing away from Earth has only been seen by the human eye from spacecraft.
B. There are many moons in the Solar System while we generally think of the Earth’s Moon only. There are moons in the solar system which orbit planets, dwarf planets, and other solar system objects. As of May 2018, there are close to 350 moons in the Solar System. There are total 175 moons which orbit 8 planets and there are 9 moons which orbit 5 dwarf planets and rest of them orbit other solar system bodies like asteroids.
C. The Moon has no atmosphere like the Earth and some other planets. This means that the surface of the Moon is unprotected from cosmic rays, meteorites and solar winds, and has huge temperature variations. That is why there are many craters from falling meteorites. The lack of atmosphere means no sound can be heard on the Moon. Moreover, due to this fact the sky always appears black.
D. Venus and Mercury are the only planets which do not have any moon. Mercury does not have any moon because Mercury is very close to the sun so it wouldn’t be able to hold on to its own moon. Any moon with a large distance from Mercury would be in an unstable orbit and will eventually get pulled into the Sun. If moon were too close to the planet they would be destroyed by tidal gravitational forces and most likely crash into Mercury.
E. Jupiter has 69 moons out of which 53 moons have been officially named. Jupiter’s four main moons are Io, Europa, Ganymede and Callisto. These moons are named the Galilean moons after Galileo Galilei. Jupiter features some of the largest moons in the solar system. Ganymede is the largest moon in the Solar System and ninth largest object in the solar system. It is 8% larger than planet Mercury. Ganymede is the only moon which is known to have the magnetic field.
