A newly discovered exoplanet has characteristics so peculiar that astronomers think it must have experienced a giant collision some time in its past.
TOI-4860b happens to orbit a tiny star, completing each lap in just 1.52 days. It joins a small number of worlds that pose a fascinating puzzle - there are currently no known formation pathways for such chonkin' planets around such small stars.
While observing the star system HD 23472 , researchers found three super-Earths and two super-Mercuries. This type last of exoplanet is still very rare—counting these two, there are only eight known super-Mercuries.
