CNN —Astronomers may have found a rare “sibling” that shares the same orbit of a Jupiter-like planet around a young star.
Two Jupiter-like planets, known as PDS 70b and PDS 70c, are already known to orbit the star.
Evidence for Trojans beyond our solar system — specifically Trojan planets — has been sparse until now.
The signal suggested a cloud of debris with a mass of about twice that of our moon, which could be a Trojan planet or a planet in formation.
A cloud of debris (circled by a yellow dotted line) may be a newly forming planet in the same orbit as the planet PDS 70b.
