By Ashton Church

A large body orbiting the sun or other star

A star such as the sun and all the objects orbiting it

A rocky metallic object that orbits the sun

A ball of ice and rock that orbits the sun

Small rocky objects that orbit the sun

The meteoroid that enters the atmosphere and burns with a streak of light

Any part of the medeoroid that reaches Earth surface

A large, hot ball of gases, which is held together by gravity

A number of stars that appears to form a pattern

The brightness of a star

The apparent shift in an object's location when viewed from two positions

The distance light travels in a year

A huge cloud of gas and dust

A star that explodes

An object whose gravity is so strong light cannot escape it

A large group of stars

The medium-sized spiral galaxy
