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

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]
