Is there any data indicating its mass, besides apparent magnitude?[edit]

For instance, the object's orbit apparently shifted after its close pass with Earth (how close seems the most notable thing about this rock); can we derive any useful estimates of its mass from its course deflection, or is its own mass a vanishingly small influence on that? Is apparent magnitude all we have to go by & if so, what volume does that potentially indicate if it's a bolide? ProphetZarquon (talk) 04:38, 2 November 2019 (UTC)[reply]

Compared to the Earth/Moon/Sun, the asteroid basically has no mass. The mass of the object would also be lost in the uncertainty in the close approach distance of ±200 km. All you can do is estimate a generic value. -- Kheider (talk) 15:54, 3 November 2019 (UTC)[reply]
