The "Oort Cloud".
It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
mars is a sphere and is rough
No; if a planet was square, the gravitational attraction from the core would be uneven. This would not happen. For that reason, all celestial bodies such as planets and comets would have a resemblance to a sphere.
A star is a massive, luminous sphere of plasma held together by gravity, which generates energy through nuclear fusion in its core. Objects that orbit a star are collectively referred to as its planetary system, which may include planets, moons, asteroids, comets, and other celestial bodies.
Every planet has a center of gravity, anda sphere is the mostgravitationally stable shape for a planet to have.
celestial sphere
comets are pieces of floating rock in the outer space while planets are a sphere shaped ball that is able to have life living on it.There are most likely thousands of planets with life some possibly more intelligent than us but we have no means at the moment to contact them or find evidence of their exsistence
The imaginary sphere that surrounds the Earth is called the celestial sphere. It is an abstract sphere of infinite radius upon which all celestial objects are assumed to lie. It provides a convenient reference frame for locating celestial objects in the sky.

No, the Oort Cloud does not have rings. The Oort Cloud is a vast region of space beyond the outer planets in our solar system where comets are believed to originate from. It consists of icy objects and debris left over from the formation of the solar system, but does not have ring structures like those found around planets.
The imaginary sphere created by scientists that surrounds the Earth is called the celestial sphere. It is used as a way to map and locate stars and other celestial objects in the sky as they appear from Earth's perspective. The celestial sphere helps astronomers describe the positions and movements of objects in the night sky.
It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
The inside of a planetarium is a sphere with the stars and planets projected on to it. The celestial sphere is an infinite sphere that we imagine has the stars and planets on it. On the celestial sphere only an object's direction matters and its distance is ignored. A viewer at the centre of the planetarium sees stars and planets as they appear in the sky, but viewers in all the seats see approximately the right view.
One of the best example of terrestrial sphere is the earth. The 8 planets are also considered as the terrestrial sphere.

"Gravity pulls the stars and planets into the shape of a sphere." "The Chinese sphere of influence extends to Europe, Africa, and the US.
