Why do planets not orbit the Sun vertically?

Planets orbit in a similar plane to each other because they were all formed from the same disk-shaped cloud of matter. There’s nothing particularly horizontal or vertical about it, since there are no orientations like that in space. It’s just how people who draw pictures of the solar system like to draw it.

Why are planets round and galaxies flat?

A planet is round because of gravity. A planet’s gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.

Do any planets orbit vertically?

Now, scientists have discovered an unusual pair of binary stars (four stars total) that appear to have created planets that orbit in a vertical plane over the poles of the stars rather than the horizontal dimension one would typically expect.

Are all the planets on the same horizontal plane?

Originally Answered: Do all the planets in the solar system really orbit on the same horizontal plane? NO.. if you place the sun, in the centre of a perfectly flat disc, that reached out as far as Pluto, the orbits of the planets would NOT all lay flat on that disc, no matter it’s orientation.

Why do all planets orbit in the same direction?

Originally Answered: Why do all the planets in the solar system rotate in the same direction around the Sun? Planets orbiting the Sun in the same direction is simply the result of the initial rotation of the ‘solar nebula’ – the cloud of gas and dust that condensed to form the Sun and planets.

Why is a galaxy flat?

Summary. As galaxies form, the collisions of objects with each other cancel their momentum in all directions except for the direction of the rotation. The stars line up around the center of rotation, creating the flat, or pancake-like shape.

Do all planets spin the same direction?

The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets’ formation.

Why is the galaxy on a flat plane?

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.

What causes a galaxy to spin?

This is due to spinning forces, such as centrifuged force. Remember that galaxies form (at least the regular ones) from the spinning of matter around a galaxy nucleus. So, you’re not wrong. Gravity is isotropic, but in this cases the spinning forces are the definition to the galaxy form.

What would you expect the orbits of the planets to look like?

You would’ve expected the orbits to be oriented randomly, since gravity — the force that keeps the planets in these steady orbits — works the same in all three dimensions. You would’ve expected something more like a swarm than a nice, orderly set of nearly perfect circles.

Why do planets form in a plane?

Because that disk of dust was a disk, all in a plane, all of the planets formed in a plane as well. Rings and disks are common in astronomy. When a cloud collapses, the conservation of angular momentum amplifies any initial tiny spin of the cloud.

Why are the large majority of stars in elliptical galaxies?

But the large majority of stars are formed in the gas after it has settled into the disk, and so the large majority of stars will be found in the same disk. So why are there even elliptical galaxies?
