It should be obvious that the planet Earth is not perfectly round, since it has mountains, valleys, and other geographical features. It also bulges at the equator, as a result of the centrifugal force of its own rotation, and is therefore an oblate spheroid rather than a sphere.
I also find it a bit strange that you refer to "your solar system" as if you come from a different solar system. As far as I know, only human beings from the planet Earth are participating in this discussion. We all come from the same planet in the same solar system. It is therefore our solar system.
In general, planets are considered round, although they may not be perfectly round. Jupiter's equatorial radius is about 71,500 km, and its polar radius is about 66,800 km, indicating that it bulges at the equator; it is a little "stouter" than it is "tall". Earth has the same general characteristic. No object in the solar system has a geometrically perfect shape, and it is not likely that any objects in the universe do, either.

They are both round, they both have gravity, they are both in the Solar System,
Because everyone from the ancient Greeks onwards knew that the Earth is round.
because it is!
No. It's more bumpy.
it is perfectly round.
The Earth is not perfectly round for at least three reasons. The first reason is that the Earth is somewhat flexible so it bulges outwards at the equator because of its rotation. The second reason is that the land masses are not distributed evenly and their weight presses down on the Earth, "dimpling" it slightly. The third reason is because geologic processes keep thrusting up mountains and erosion keeps digging out valleys so the Earth cannot be perfectly smooth.
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).
the sun is round but not a perfect sphere.its surface is bumpy.

Mercury is definitely not perfectly round. All of our photos of Mercury show that it's covered in craters which cause ridges to form all over the planet. This means that it's not perfectly round.
