(SCIENCE ALERT) -- There may be multitudes of Earth-like planets sprinkled throughout the Milky Way galaxy, but they are not so easy to find. To date, only around a third of the over 4,000 exoplanets found and confirmed are rocky - and most of those are within a few thousand light-years of Earth.
So the announcement of a new rocky exoplanet is always exciting -- but this particular newly discovered rocky exoplanet is even more exciting yet.
It belongs to the much smaller subset of rocky exoplanets that orbit at an Earth-like distance from its star. And it's a whopping 24,722.65 light-years away from us - which could make it the most distant Milky Way exoplanet discovered yet.
