Thanks to the very small size of the star – which is only slightly bigger than planet Jupiter – it should be possible to detect the atmosphere of this exoplanet, if it has one, using the James Webb Space Telescope.Ī new terrestrial world in a multi-planetary system
“The similarity in the properties of LP 791-18 d and Earth as well as the prospect of detectable geological activity and volcanism on it make it a key object to better understand how terrestrial worlds form and evolve.” “The discovery of this exoplanet is an extraordinary find,“ said Professor Björn Benneke from UdeM’s Department of Physics. Observations of this exoplanet and another one in the same system indicate that LP 791-18 d is likely covered with volcanoes similar to Jupiter’s moon Io, the most volcanically active body in our Solar System. This planet, named LP 791-18 d, has a radius and a mass consistent with those of Earth.
