What is the shape of an Oort cloud?
spherical
Unlike the orbits of the planets and the Kuiper Belt, which are pretty flat like a disk, the Oort Cloud is a spherical shell surrounding everything in our solar system. It’s like a bubble with a thick shell. The Oort Cloud is made up of icy pieces of space debris.

Why is the Oort cloud spherical?
The estimated mass of the cloud is only a small part of the 50–100 Earth masses of ejected material. Gravitational interaction with nearby stars and galactic tides modified cometary orbits to make them more circular. This explains the nearly spherical shape of the outer Oort cloud.
Is the solar system flat?
Our solar system is actually pretty flat, with most of its planets orbiting within three degrees of the plane of the Earth’s orbit around the sun, called the ecliptic. It’s out of this rotating protoplanetary disk of gas and dust that planets are born, resulting in a relatively flat solar system.
What formed the Oort cloud?
In short, gravity from the planets shoved many icy planetesimals away from the Sun, and gravity from the galaxy likely caused them to settle in the borderlands of the solar system, where the planets couldn’t perturb them anymore. And they became what we now call the Oort Cloud.

How did the Oort cloud form?
What is the Oort cloud important?
The Oort cloud is the proximate source of observed nearly parabolic, so-called ‘new’ comets entering the planetary region, and is also the presumed source of the long-period comet flux and the majority of Halley-type comets (HTCs).
Is the solar system a sphere?
While all the planets in our solar system are nice and round, some are rounder than others. Mercury and Venus are the roundest of all. They are nearly perfect spheres, like marbles. But some planets aren’t quite so perfectly round.
Why is the solar system disk shaped?
It’s thought to have arisen from an amorphous cloud of gas and dust in space. The original cloud was spinning, and this spin caused it to flatten out into a disk shape. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.
