Space

The solar system is made up of the Sun and the objects that orbit around it, including planets, asteroids and comets. The Sun’s gravity holds all of these objects together.

The Sun is our nearest star. It is a yellow dwarf star and is found at the centre of our solar system.

Days, years and months are periods of time which are determined by the movement of Earth around the Sun, and the movement of the Moon around Earth.

A Moon phase is the shape of the visible part of the Moon, and this changes gradually over the course of a lunar month.

Scientists and astronomers often use units called light years to talk about the enormous distances to distant objects, such as stars and galaxies.
