Not all Planets are round. Some dwarf planets are not round
Round is a good shape. The force of gravity collapses matter into a spherical shape, once there is enough of it. Small bodies of normal solid matter less than a hundred miles across lack sufficient mass to pull them into a spherical shape.
There are no planets orbiting the Earth because all eight of them orbit the Sun. But the Moon orbits the Earth, and all it does is go round and round in a rather complicated orbit which is disturbed by the Sun's gravity.
because of the gravity of the other planets around them
Yes, dwarf planets can be round. Like regular planets, dwarf planets are large enough for their own gravity to pull them into a nearly spherical shape, making them round. Examples of round dwarf planets include Pluto and Eris.
The circumference of a planet is the distance round their widest part. On earth, it is measured round the equator.
The large round object you’re referring to is a dwarf planet, specifically Pluto. Unlike full-fledged planets, dwarf planets like Pluto have not cleared their orbital neighborhoods of other debris. This classification is part of the definition established by the International Astronomical Union (IAU) in 2006.
the earth is not perfectly round, as with most other planets it is an oblate spheroid. Answer: The tilt refers to a tilt in the axis of rotation, compared to a line that is perpendicular to the Ecliptic (the plane of Earth's orbit around the Sun).

Please kindly note planets revolve round the sun only.
Astronomers do not create planets, they observe and study them. A "dwarf planet" is defined as large enough to be round, but too small to have cleared its orbit "neighbourhood" of other objects.
Because SEASONS are caused by the tilt of a planet's axis of rotation (spin) as compared to the plane in which the planet orbits (goes round) the Sun. Earth has an axial tilt and so do MOST of the other planets. This means that these planets will also have seasons.
Our moon requires 27.3 days to orbit the earth. No other moon orbits our earth--they orbit other planets.

Copernicus
The planet Mars is round in shape. All of the planets in our solar system are orbits. The gravitational pull of the sun has formed the planets to be around.
