New ESO research has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the planet has a neighbor. “Being able to measure the mass and density of K2-18b was tremendous, but to discover a new exoplanet was lucky and equally exciting,” says lead author Ryan Cloutier, a PhD student in U of T Scarborough’s Centre for Planet Science, U of T’s Department of Astronomy and Astrophysics, and Université de Montréal Institute for research on exoplanets (iREx).
Both planets orbit K2-18, a ...
