Venus, it is slightly smaller, and much hotter
With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).
From the Sun:Mercury is innermost and smallest (about the size of our Moon.)Venus is next and almost exactly the size of the Earth, just a shade smaller.Earth is next and it is - well- the Earth!Mars is the last of the rocky - Earthlike planets and it is smaller than Earth.See a picture comparing the sizes at: http://en.wikipedia.org/wiki/File:5_Terrestrial_planets_size_comparison.png
The Earth's inner core is increasing in size as the planet cools.
Earth is the 5th largest planet in our solar system, but the largest planet in the inner planets (Mercury, Venus, Earth, Mars.)
Yes, Earth is the largest of all inner planets in our solar system. The inner planets, also known as terrestrial planets, include Mercury, Venus, Earth, and Mars, and Earth is the largest in terms of both size and mass.
Earth.
Venus because it is almost the same size as Earth.
Venus.Venus is Earth's Twin. It is almost exactly the same size but is so hot it can't even get close to supporting life. The gasses on Venus are very deadly and it is said Venus has no ground. Very interesting stuff, my friend.
Eris is an OUTER planet. The only inner planets are mercury, venus, earth and mars. An outer planet is not related to the size of the planet but rather the distance from the sun.

No planet is exactly the size of Earth. Venus is close to Earth's size but slightly smaller.

Venus is a rocky inner planet, so it is terrestrial.
I assume you mean "planet". That would be Venus.
