No,because not all the planets are the same.
All planets in our solar system have elliptical orbits.
The planets or other cosmic objects are very different, not similar.
In our solar system, the inner four planets, Mercury, Venus, Earth, and Mars, are referred to as rocky, or terrestrial ("Earth-like"). Outside the solar system it is estimated as many as 40 billion planets in our galaxy alone would be similar to Earth.
Within our solar system all the planets are unique. Within the universe, it is likely that there will be planets very similar to those in our solar system. This would mean that no planet is actually unique. However we can not prove this yet.
If you mean in our Solar System: All of them. All are elliptical, but all are very close to a circle.
The inner planets are mostly composed of heavier elements than the gas giants because those materials gravitated closer to the sun when the solar system was forming.
All planets in our solar system have elliptical orbits.
They are both planets in our Solar system.

Probably Venus and Earth.
That's the age of our Solar System, so you can expect all the planets in our Solar System to have approximately that age.
Earth and Mars are the planets in this solar system with similar rotation speed of approximately 24 hr.
No it's a rocky planet similar to that of Earth. The first four planets our solar system are terrestrial.
Anywhere there are stars. Hundreds of planets have already been discovered outside our own Solar System.
The circulatory system, like the water system, continually reuses the same materials.
Both are planets, both orbit the Sun. Other than that, they are QUITE different.
