What would happen if the moon broke apart?
If the moon exploded, the night sky would change. We would see more stars in the sky, but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter, and our ocean tides would be much weaker.
How many planets are there in 2020?
Constant Contact Use. There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
What planet is rocky?
There are four rocky, or terrestrial, planets: Mercury, Venus, Earth, and Mars. These planets are called terrestrial planets because they are made up of rocks and metals and have solid surfaces. But even though they’re made of the same materials, the four rocky planets in the Solar System aren’t the same.

Is the solar system made up of 8 planets?
Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.
Is there a 10th planet?
With the exception of some long-period comets, until 2018 VG18 was discovered on December 17, 2018, Eris and Dysnomia were the most distant known natural objects in the Solar System. Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System’s tenth planet.
Which planet is smallest?
