The Sun
Sun
An ordinary yellow star, the only one close enough to see as a disc — 109 Earths across, and eight minutes away at the speed of light.
Did you know
Never look at it directly, or through binoculars or a telescope without a proper solar filter: it will blind you in an instant.
Science
Every second it turns about four million tonnes of matter into light. It is about halfway through its life.
