"A team of astronomers has discovered the most-distant body ever observed in our Solar System. It is the first known Solar System object that has been detected at a distance that is more than 100 times farther than Earth is from the Sun."
https://carnegiescience.edu/node/2428 “Farout” is at about 120 astronomical units, its brightness suggests that it is about 500 km in diameter (likely making it spherical) and it has a pinkish hue, a color generally associated with ice-rich objects. Very nice discovery. Regards Marc. |

He is a link to the Minor Planet Center's Electronic Circular for this object, posted today:
E2018-Y14 Note that the Delta (distance from Earth in AU) and the r (distance from sun in AU) are run together. For November 17th those values were 124.3330 and 125.2666 respectively. Also there is this which is a little more readable: 2018 VG18 In the orbital elements section the q (perihelion) is currently listed as 21.739 AU so it was closer at some point decades ago. But all those orbital elements are still pretty uncertain. It's currently on the way out on its orbit. |
