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.

Planets travel in elliptical orbits.
There are four planets called the "inner planets".Of those, Mercury is the innermost planet.From the sun the planets areMercuryVenusEarthMarsJupiterSaturnUranusNeptunePluto
This is not known yet. Hundreds of planets have already been found outside our Solar System, but earthlike planets can, for the most part, not be observed with current technology.
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.
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.
that question cannot be answered but i can answer how many planets in the solar systems there are 8 planets these are: Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune to memorize it you could use this simple acronyms my very excellent mother just sent us nachos
by observing the slight dip in brightness of the central star as the planet transits
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.

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.
possibly.
Yes, we have found evidence of planets orbiting neutron stars. A planet similar to Earth in size and mass could exist around a neutron star, but beyond that it would not be very Earthlike. Such planets probably form from the remains of the supernova.
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
