Astronomers from the Center for Astrobiology in Madrid, Spain, using the Atacama Large Millimeter Array, have discovered a possible sister planet orbiting a star 400 light-years away from Earth.
They discovered that a planet outside the solar system and its brother are located in the BDS 70 system, which is a star in the constellation “Centaurus” and is about 10 million years old.
If confirmed, this discovery would be the strongest evidence yet that two exoplanets could share a single orbit.
Two decades ago, it was theoretically predicted that pairs of planets of similar mass might share the same orbit around their star, the so-called Trojan planets or co-orbital planets.
“Trojans, rocky bodies in the same orbit as a planet, are common in our solar system, and the most famous example is the Trojan asteroids of Jupiter, more than 12,000 rocky bodies in the same orbit around The sun is like a gas giant.
