Talk:Three Earths

For Mars, all you need is a larger core to keep the planet going. I am not sure how you can do this, but you could try to say that in the early bombardment peroid, the planet was hit many more asteroids and helped its core become larger and be active to this day. The planet might grow because of this, around 1000-2000km larger mesuring its diametre.

Now, for Venus, all you really need is a smaller atmosphere and a magnetic field slightly larger than Earth's. And walla, you have a "normal" Venus. Thoughts? :D Imp (Say Hi?!) 16:00, August 26, 2012 (UTC)
