Inner Planets

The Inner Planets, or known as the terrestrial planets, are 4 planets that are closest to the sun. The four inner planets are Mercury, Venus, Earth, and Mars. These four are smaller than the things behind them, but they are more warmer than the Gas Giants, or the Outer Planets. The Inner Planets are made enterally out of rock, dust, and other space rocks. Some of the Inner Planets have moons, or satellites. Mars has the most moons out of the 4. Mercury and Venus don't have any natural satellites. The only Inner Planets with satellites are Earth and Mars (Earth has one natural satellite and Mars having a total of 2 satellites). The larger the planets are, the more mass and gravity they will have. Earth is the largest Inner Planet so it has the most mass and gravity. And Mars had the third most gravity of the Inner Planets, but if it has less gravity, then it does not have a lot of moons, right? well, the reason Mars has more satellites than the Earth is because of it's position. Mars is the closest planet to the Asteroid Belt, and that is where most satellites come from. But, instead, Mars's moons are a lot smaller than our moon, Luna. When a planet gets a satellite, a asteroid from the Asteroid Belt must come out of orbit and head towards that planet, then, the planet must have enough gravity to grip on to the asteroid, then, if the planet grips on to it successfully, it will be known as a moon, or a natural satellite.

Nicknames and Names of Moons from the Inner Planets

Now, do you have a nickname? well, so do the planets.

Mercury = Its nickname is the Swift Planet and has no natural satellites or moons.

Venus = It has 2 nicknames, The Morning Star and The Evening Star and has not natural satellites or moons.

Earth = Its nickname is the Blue Planet and has one natural satellite or moons and its name is Luna.

Mars = Its nickname is the Red Planet and has two natural satellites or moon and their names are Phobos and Deimos.

Mercury is called the Swift Planet, because of its speed and it only takes Mercury 88 Earth days to make one complete orbit around The Sun. Venus is called the Morning and the Evening Star because of its brightness, Venus is the second most brightest object in the sky and is the most brightest planet in the entire Solar System. Earth is called the Blue Planet, because of its oceans, seas, lakes, and tides. Mars is called the Red Planet because of its Red color. Mars has something called iron oxide that helps give out its red color. Mercury and Venus don't have moons because if Mercury had a natural satellite, the Sun would probably take the sattelite away and demolish it because of it's gravity, and Venus would not have a moon because since Venuse has a very thick atmoshpere, the asteroid or moon would instantly burn up in the thick atmosphere or the intense heat of the planet.
