If by "like Earth" you mean habitable (that we could live on, without spacesuits, domes or other technological adaptations): there aren't any in our solar system, and none yet elsewhere that we know of. But scientists keep searching; the universe is a pretty big place, and odds are there are multiple other Earthlike planets out there somewhere.
All of them.
There is no maximum number, and "nebular theory" has been knocked for a loop by the recent discoveries of 400+ "extra-solar planets" - planets orbiting other stars. Classical theories predicted that planetary systems would be rare; however, it seems that every nearby star we've looked at recently has been discovered to have planets - LOTS of planets.

All of the others were. But each one got its own special name.
Planets travel in elliptical orbits.
The Kepler mission used the transit method to detect Earthlike planets around other stars. It observed the slight dimming of a star's light when a planet passed in front of it, indicating the presence of an orbiting planet. By monitoring these periodic dips in brightness, Kepler could infer the presence of planets, including Earthlike ones, by analyzing the data over time.
The inner planets are called terrestrial because they are Earthlike: small and rocky planets as opposed to the outer planets which are giant gaseous planets,The word terrestrial comes from the Latin word terra, meaning Erth.
Well, I'm not sure but I read in a book that in year 2015 a spacecraft named Darwin will be launched to look for Earthlike planets. Onboard telescopes will then analize the light from the planets that might have been produced by living things.
There are billions of planets in the universe, with estimates ranging from 100 billion to 200 billion planets in the Milky Way galaxy alone. Beyond our galaxy, there are billions more galaxies with their own planets, making it impossible to determine an exact number of planets in the universe.

It is estimated that there are billions of stars in the Milky Way galaxy that could potentially have Earth-like planets within their habitable zones. The exact number is difficult to determine with certainty due to the vastness of our galaxy and the limitations of current technology.
Mars already has an atmosphere. It is not known how long creating an Earthlike atmosphere because we do not have the ability to terraform planets and we do not know all of the challenges it might hold.
Neither of them have rings, and they also have impact crates from collisions of the planets with objects primarily made of rock 2nd Answer: Also the Terran (Earthlike) planets are rocky while the Jovian planets are mainly composed of different gases.
possibly.
It's a "terrestrial" planet, because it is rocky with an iron core, like planet Earth. "Terrestrial" means "Earthlike". Jovian planets are mainly made of gases and liquefied gases.
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 word "geode" is derived from Latin meaning "earthlike," a reference to their rounded shape.
