TRAPPIST-1 e
Exoplanet
A rocky planet in that system, orbiting where water could stay liquid if it holds on to the right atmosphere.
Can you see it tonight?
Where are you?
To work out whether you can see this tonight, we need to know roughly where you are looking from. Your position stays in your browser: it is never sent to us, never stored and never shared.
Without it, everything else on this page still holds: what this object is, where it sits on the sky, and where every fact came from.
What it looks like
A photograph of this patch of sky, taken by a telescope on the ground. It shows TRAPPIST-1, the star that TRAPPIST-1 e orbits, because the planet itself is far too small and faint to appear separately.
Brightness adjusted so faint detail shows. Every picture here is a rendering of the survey's measurements rather than a measurement itself, and this is the same setting for all of them.
