What are the forces that give asteroids their shapes? And what shape do neutron stars that do not rotate around its axis have?

Chronos said:Neutron stars spin to conserve the energy released by the supernova explosion that preceeded them. They typically spin very fast. My argument [and I allow for the possibility I am wrong] is the explosion is assymetric and imparts a huge amount of angular momentum on the fragment.
Chronos said:OK, I'll bite, ST. Does not accretion from a binary partner tend to slow down the rotation of a neutron star. I'm thinking tidal forces. Humm, it just occurred to me it can also have a spin up effect... astrophysics can be so confusing sometimes...
Chronos said:Agreed, the accreting mass would be a trivial effect.
James R said:And about those asteroids...
The shapes of asteroids are fairly random. They are usually too small for gravity to play much of a role. Their shapes are determined by the random way their contents happen to come together, as well as what hits them in their travels.
Doh! I get it now. My denseness sometimes rivals a neutron star.SpaceTiger said:Actually, I'm saying it wouldn't be. Tidal dissipation would be a trivial effect.
Asteroids are small, rocky objects that orbit the sun, while neutron stars are extremely dense celestial bodies that are the collapsed cores of massive stars.
Asteroids are believed to be remnants of the early solar system, while neutron stars are formed when a massive star dies in a supernova explosion and its core collapses.
We can study asteroids using telescopes, spacecraft, and radar imaging. Neutron stars can be studied through observations of their radio emissions, X-rays, and gravitational waves.
Most asteroids have irregular shapes, often resembling potatoes or rocks. However, some larger asteroids can have more spherical shapes.
Yes, scientists use mathematical models and data from observations to predict the trajectory of asteroids and the behavior of neutron stars. However, these predictions are not always entirely accurate due to the complex nature of these objects.
