Astronomers discover Sun like planet-eater

The star has been named after a Greek mythological character, Titan, who ate his own children including Poseidon (well known as the planet Neptune), Hades (Pluto) and three daughters is 350 light years away from planet earth.

The researchers Semyeong Oh, astrophysicist at Princeton University in New Jersey and co-author David Hogg from the Flatiron Institute in New York stated that they didn’t intend to search a planet-eater and were instead analysing a catalog of new star data for pairs of stars with similar speeds and trajectories. But it led to the discovery of Kronos and its lesser known brother, Krios.
