1.  Our solar system has inner and outer planets.  Also our solar system has a dwarf planet.  All of our planets revolve around our central star, or in other words, a sun.

2.  The sun is the central star of the Milky way galaxy.  Without the sun we would not be alive.  Our sun provides us with light, heat, and energy to live.

3.  Mercury is the size of Earth’s moon.  Mercury is covered with craters.  Mercury is the closest planet to the sun.

4.  Venus is the same size as Earth.  Venus is also the third brightest object in the sky.  Venus is made of volcanoes, lava plain, craters, mountain ranges, and highland regions.

5.  Earth is the planet we live on.  Earth is the largest inner planet.  Earth’s distance from the sun helps the temperature maintain so it can support life.

6.  Mars is also called the Red Planet.  Mars has two moons Deimos and Phobos.  Mars is very small compared to earth.

7.  The asteroid belt is in between the outer and inner planets.  The asteroid belt is made of rocks and other pieces of stuff.

8.  Jupiter is the largest planet in our solar system.  Jupiter has at least 63 moons or more.

9.  Saturn has rings around it.  Saturn has at least 31 moons.

10. UUranus is a gas giant. UUranus is sideways when it orbits the sun.

11.  Neptune is one of the windiest places in our solar system  It has at least 13 moons.

12.  Pluto is a dwarf planet.  Pluto used to be considered a planet but now its considered a dwarf planet.

13.  A planet is a big object that orbits a star.  Earth is a planet.

14.  The inner planets are Mercury, Venus, Earth, and Mars.  The inner planets are the ones before the asteroid belt.

15.  The outer planets are Jupiter, Saturn, Uranus, and Neptune.  The outer planets are the planets after the asteroid belt.

16.  A comet is a ball of ice, rock, and frozen gases.  Usually comets are less than 10 kilometers across.

18.  During the moon phases there is waxing and waning.  When you look at the moon you think there are different shapes of it but it is just the moon phases.

19.  A galaxy is a huge system of stars, dust, and gas.  The galaxy we live in is called the milky way.

20.  This is the powerful telescope called Hubble.  There are regular telescopes also but you can only see stars with them.

21.  A universe is everything that exists in space.  There are galaxies and a whole lot of stars in the universe.

22.  Stars are huge superheated gases.  The color of the star tells how hot the star is.
