Asteroids are generally not spherical; they often have irregular shapes due to their small size and the lack of significant gravitational forces to mold them into a round form. While some larger asteroids can be somewhat rounded, many have bumpy, elongated, or potato-like shapes. Their surfaces can also be heavily cratered and rugged, reflecting their history of collisions and space weathering.

How come all of the planets are spherical?
No planet is spherical, that would imply they are completely smooth. All Planets are roughly spherical because of the process of planetary formation. That is that asteroids group together under the influence of gravity, this cluster of asteroids would have its own gravitational field, and therefore attract more asteroids. More asteroids means more gravity, which means still more asteroids. So you get this runaway effect where more and more asteroids are being drawn together while the asteroids in the middle are starting to get squashed. Once you have a big enough ball of asteroids it becomes a good estimation to say 'It's roughly spherical'. If the ball is massive enough it can even start pulling in the surrounding gasses, forming an atmosphere.
Are the moons of mars deformed figures?
The moons of Mars are captured asteroids. They are not spherical, but are irregularly shaped, just like most asteroids.
Asteroids have irregular what?
Asteroids have irregular shapes due to their formation process and lack of gravitational forces to pull them into a spherical shape.
How do planets develop their spherical shape?
Gravity pulls the asteroids into spheres when they get big enough.
What object is least likely to have a spherical shape?
Mercury has about the most perfectly spherical shape, but Saturn has the leastspherical shape (next least spherical is Jupiter).
Why is the earth spherical in shape while most asteroids and comets are not?
Earth is much more massive than asteroids and comets, and thefore has much stronger gravity, which pulls it into a spherical shape. Most asteroids and comets do not have strong enough gravity to do this.
What are asteroids shaped like?
Asteroids have many shapes, depending on their mass or composition. The largest are spherical, but others and elongated spheres, potato shaped and even resemble peanuts. Mostly, they are irregular shaped rocks.
What makes an asteroid different from a dwarf planet?
Generally it's the size. If an asteroid were to be big enough to achieve hydrostatic equilibrium (approximately spherical in shape), then it may be classed as a dwarf planet, such as Ceres. Asteroids are generally too small to active this shape under their gravity so are not classed as dwarf planets.
What objects are nearly spherical in shape but share their orbital paths with other objects that are similar in size?
You can't be referring to "asteroids", because only the largest few are spherical, and they vary WIDELY in size and shape. About 60% of all asteroids orbit in the "asteroid belt", an enormous toroidal area between the orbits of Mars and Jupiter. The other 40% of known asteroids do NOT orbit in the asteroid belt.Probably the answer is "dwarf planets" although they share their orbital neighborhoods rather than their actual orbits.
What are inner planet shapes?
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
What is the surface area of an asteroid that is 4 miles across?
If you assume the asteroid is spherical, use the formula for the surface of a sphere: 4 x pi x radius2. However, at such a small size, asteroids will usually not be spherical, so this is just a rough approximation.
How does an asteroid differ from a planet?
A dwarf planet is larger, big enough to make itself into an approximately spherical shape. Asteroids are smaller and more irregular in shape.
