March 29, 2023

New observations from the James Webb Space Telescope reveal that TRAPPIST-1b is unlikely to have an atmosphere wrapped around its rocky body.

About TRAPPIST-1 b:

It is a hot rocky exoplanet orbiting an ultracool red dwarf star TRAPPIST-1.
It is the innermost of seven known planets in the TRAPPIST-1 system.
It has 1.4 times the mass and 1.1 times the radius of Earth.
It orbits its star at a distance of 0.011 astronomical unit (AU), completing one circuit in just 1.51 Earth days.
It receives about four times the amount of energy that Earth gets from the Sun.
TRAPPIST-1b is tidally locked, meaning that one side of the planet always faces the star, and one side looks away.

What is an astronomical unit (AU)?

An AU is the average distance between Earth and the Sun, which is about 93 million miles or 150 million kilometres.
It is usually used to measure distances within our Solar System.
