Our nearest star
This huge ball of superhot gas is 1.4 million kilometres across, equal to 109 Earths set side by side. With a mass of 2 million-trillion-trillion-trillion kilograms, it weighs as much as 330 000 Earths. About 1 300 000 Earths would fit inside the Sun.
Although it seems small when seen at sunrise or sunset, this is only because the Sun lies about 150 million km away from us. At this distance, it takes about 8 minutes for sunlight to reach us – even when it is travelling at about 300 000 km/s. This means that we see the Sun set eight minutes after the event has actually taken place!
