Size?

Using H=12.5, and albedo between 5%-20%, a full phase diameter estimate comes out as 8 to 20 km, small, but much larger than Oumuamua. Tom Ruen (talk) 01:07, 11 September 2019 (UTC)[reply]

But the object has been confirmed to be a comet so you can not use the asteroid scale. -- Kheider (talk) 01:12, 11 September 2019 (UTC)[reply]

Distance detected?

Roughly how far away was this object when it was first detected? And, why didn't PanStarrs find it?

JPL orbit

JPL small body database browser has e=3.52161 +/- 0.19684, a=-0.817754 +/- 0.045762, I calculate v infinity as 32.9 km/s using the latter. Agmartin (talk) 22:41, 11 September 2019 (UTC)[reply]
