Space-the area that surrounds the planets and stars
Galaxy-large group of stars, dust, gas and dark matter held together by gravity. They vary in size with some containing millions of stars while others could contain as many as a trillion. They can also form in different shapes such as elliptical galaxies and spiral galaxies
Expand-when the space between two objects gets bigger
Gravity-is a thing that keeps objects grounded and not floating around. There is none of this in space.

Solar System-The solar system includes the Sun and all the objects that orbit around it due to its gravity, including Earth.
Planet-A planet is an object orbiting a star that is large enough to be rounded by its own gravity. It is also gravitationally dominant in its orbital area but not large enough to cause thermonuclear fusion (like stars do). There are eight planets in the Solar System.
Orbit-when an object circles a planet it is called an orbit.

Moon-The Moon is a natural satellite which orbits the Earth. It is around a quarter the size of Earth and can be easily seen in the night sky. While other planets in the Solar System have ‘moons’, they are usually referred to by name, such as Jupiter’s Ganymede, or as natural satellites.
Spaceship-a rocket based form of transportation.
Rocket-used to blast spaceships into outer space.
Rocket Launch-the pad where rockets take off from.

Star-A star is a huge, bright ball of burning gas that is held together by gravity. Stars contain mostly hydrogen as well as helium and smaller amounts of other elements. The Sun is the closest star to Earth.
Constellation-a group of stars makes up shapes and objects is called a constellation.
Telescope-a peice of equipment humans use to look out into space and to look at stars and planets.
