Everything in the sky

Every object this site holds, in the order the universe holds them: our own star system first, then our galaxy, then everything past it. Each one has a page saying what it is, whether you can see it, and where to look.

104 objects. 30 of them you can see with nothing but your own eyes; another 31 are within reach of a small telescope. The rest are here because the sky would look emptier without them.

👁️ Just the ones you can actually see 🌙 What is up tonight?

In the solar system

Everything held by our own star — the planets you can find tonight, their moons, the rubble left over from building them, and the handful of machines we sent out after them.

In the Milky Way

Our own galaxy: the nearest stars, the clouds where new ones are being made, the wreckage of the ones that died, and the black hole at the middle of it all.
