Witryna16 paź 2024 · Rubble-pile asteroids like Bennu are celestial bodies made from lots of pieces of rocky debris that gravity compressed together. This kind of detritus is produced when an impact shatters a much larger body (for Bennu, it was a parent asteroid around 60 miles [about 100 km] wide). Bennu, for contrast, is about as tall as the Empire …
Witryna23 kwi 2015 · 1 Answer Sorted by: 1 At a certain size, huge asteroids get classified as dwarf planets. Pluto has an atmosphere 100,000 times thinner than Earth, and Pluto is already one of the two largest dwarf planets known. Asteroids (like everything) do have gravity, so nearby gas would be drawn to them. Apart from a few asteroids whose densities have been investigated, one has to resort to enlightened guesswork. See Carry for a summary. For many asteroids a value of ρ~2 g/cm has been assumed. However, density depends on the asteroid's spectral type. Krasinsky et al. gives calculations for the mean densities … Zobacz więcej For most numbered asteroids, almost nothing is known apart from a few physical parameters and orbital elements.
