is a pretty weird place to start with, but in 2020 astronomers found six objects orbiting Sagittarius A* that are unlike anything in the galaxy. They are so peculiar that they have been assigned a brand-new class – what astronomers are calling G objects.
The original two objects – named G1 and G2 – first caught the eye of astronomers nearly two decades ago, with their orbits and odd natures gradually pieced together over subsequent years. They seemed to be giant gas clouds 100But G1 and G2 weren't behaving like gas clouds.of the University of California, Los Angeles explained in 2020.. Based on that data, a team of astronomers led by UCLA astronomer Anna Ciurlo identified four more of these objects: G3, G4, G5, and G6.
They're on wildly different orbits from G1 and G2 ; all together, the G objects have orbital periods that range from 170 years to 1,600 years.– that is, the closest point in its orbit to the black hole – was, Ghez believes, a big clue."We had seen it before, but it didn't look too peculiar until it got close to the black hole and became elongated, and much of its gas was torn apart.
