A mega comet has entered our solar system. Named 2014 UN271, the object will approach the Sun and reach Saturn’s orbit in 2031.
It is estimated to be 100 to 370 km wide, and this object is larger than the typical feature of a comet, making it more likely to be a dwarf planet.
This illustration shows the distant Comet Bernardinelli-Bernstein as it might look in the outer Solar System. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path.
