The figures below show several different astronomical objects. rank the objects based on the amount that spacetime is curved (relative to flat spacetime) very near the surface (or event horizon) of the objects, from least to greatest.
1. red giant
mass = 1msun
radius = approximately 100 rsun
2. white dwarf
mass = 1msun
radius = approximately 0.01 rsun
3. the sun
4. black hole
mass = 1msun
radius (event horizon) = approximately 3km
