How large is TRAPPIST-1c compared to Earth?

TRAPPIST-1c is a terrestrial planet that is roughly 1.1 times the radius of Earth. This makes it incredibly similar in size to Venus, making it an exciting subject for planetary scientists.

What telescope discovered the TRAPPIST-1 star system?

The star system was initially discovered by the TRAnsiting Planets and PlanetesImals Small Telescope (TRAPPIST) located in Chile in 2015. Later, the Spitzer Space Telescope provided crucial follow-up data to confirm the presence of seven planets in the system.

Does TRAPPIST-1c have an atmosphere?

Recent observations from the James Webb Space Telescope (JWST) suggest that TRAPPIST-1c likely lacks a thick, Venus-like carbon dioxide atmosphere. Researchers are still studying it to determine if it has a thinner atmosphere or no atmosphere at all.

How long is a year on TRAPPIST-1c?

A year on TRAPPIST-1c, defined as the time it takes to complete one full orbit around its host star, is only about 2.42 Earth days. It sits incredibly close to the ultracool dwarf star TRAPPIST-1.
