The HIP68468 solar twin has been spotted by astronomers and is said to have a lot of similarities to the sun.

Astronomers spotted the star using a 3.6-meter telescope at the La Silla Observatory in Chile, according to the Christian Science Monitor.

HIP68468, a star that’s known to have destroyed some of its own planets, is giving scientists new insight into the “evolution and life cycle of star system,” CSM reported.

Astronomers took a deeper look at star HIP68468 while trying to discover planets that orbit solar twins, which are stars that are considered to have similarities to the sun.

While studying this star, researchers discovered a great amount of lithium as well as many other elements, which was abnormal, considering the stars’ long existence.

HIP68468 is 6 billion years old and has four times the amount of lithium expected for a star that age, according to the University of Chicago's UChicago News website.

The amount of lithium found in HIP68468 suggests the star might have eaten or destroyed the planets around it.

“It can be very hard to know the history of a particular star, but once in a while we get lucky and find stars with chemical compositions that likely came from in-falling planets,” Debra Fischer, a professor of astronomy at Yale University said, per UChicago News. "That’s the case with HD68468. The chemical remains of one or more planets are smeared in its atmosphere.

“It’s as if we saw a cat sitting next to a bird cage. If there are yellow feathers sticking out of the cat’s mouth, it’s a good bet that the cat swallowed a canary.”

Megan Bedell, a University of Chicago doctoral student who is co-author of the research, said the team of researchers plan “to study more stars like this to see whether this is a common outcome of the planet formation process.”
