Either way, the larger object is about 2,300 times heavier than its partner.
The team calculated systemstransverse velocity, or the amount it moved across the sky, to determine its speed.

That would mean the rogue planet and exomoon model is favored.
Based on the systems superlative speed, it may be a hypervelocity star system.
Exoplanets are worlds that exist beyond our solar system.

They come in many shapes and sizes; some are so-called super-Earthslarge rocky worlds like our own planet.
Several years ago, the Webb telescoperevealeda familiar exoplanets atmosphere in sharper detail than ever before.
Last September, astronomersidentifiedone of the most massive exoplanets ever found.
