There are 7 Earths in universe exactly the same of our earth it is mention in the holy books

No way, there must be many, many planets throughout the universe that are similar to our own and support life. There are probably many others that support life that is much different than we are accustomed to also.

Do you really mean plants? If so there are quite a few.\nIf you meant planets then most people say 9, although there is a big controversy about what makes something a planet. We have discovered another named Sedna and a couple more that may eventually be called planets.

Our solar system now has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.\nThey are arranged outward from the sun as I've listed them.\nThat is with Mercury closest to the sun.\n\nWe also have three "Dwarf Planets"\nCeres, Pluto, and Eris.\nCeres being closest to the sun.

i don't know anything about this book or author.  it is bogus so forget it.\n\nthere is one star (sun), eight planets (mercury, venus, earth, mars, jupiter, uranus, and neptune), hundreds of dwarf, ball-shaped bodies ("1 ceres", "134340 pluto", and "136199 eris" for example), and tens of thousands small irregularly-shaped bodies in the solar system, and there is no hint of another star or any more planets.\n\nhttp://en.wikipedia.org/wiki/Extrasolar_planet\nhttp://exoplanet.eu/catalog.php\n\nin 2006,  astronomers found evidence for a planet orbiting a star 21,500 ± 3,300 away.  the star is cataloged as OGLE-2005-BGL-390L.  the planet, OGLE-2005-BGL-390Lb, is 5.5 earth masses, but astronomers have also found more than 200 others.

We're still working on trying to find planets, and so far are up to about 100 for sure. Finding moons around those planets is something that's currently beyond us, but it's likely that many of them do have moons. In a galaxcy our size, there could easily be trillions of planets with trillions of moons, but we have no way to know at present.

Jupiters the biggest in our solar system, but the universe is pretty effing big.  There are probably billions of planets in the universe.  Ask God.

10 is my answer. A new planet call UB313 was discovered. Here are they planets in order:\nMecury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.\n\n10 Planets said. 10 Points for the best answer

Our own solar system has 10 planets that we know of:\nMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and the newly discovered 2003 UB313.  That last one is still being contended, and why that debate gets so heated is beyond me.\n\nThere are actually 155 known extrasolar planets, and that number is only going to rapidly increase.  You can find a list on the California & Carnegie Planet Search site below:

The earth consists of 91 or 92 natural elements in many varied combinations. There is no one formula for the earth.

we already found a 10th planet in our solar system, but it's still unclear if it's considered as planet (some say it is too small).\nThe name of the "10th planet" is Sedna.

Actually there is only one universe which encompasses everything: "All matter and energy, including the earth, the galaxies, and the contents of intergalactic space" - http://dictionary.reference.com/search?q=universe\n\nThe earth is part of a galaxy which we call the 'Milky Way'.

I doubt that Earth is the only planet in the whole Universe that can sustain life.  There will probably be some other planets out there somewhere with some sort of life on it.  Whether it's intelligent life or not is another question!\n\nThere may very well have been life on Mars, or on other planets in our solar system at one point,  but we have yet to find it, or any evidence.

Universe in general is the area of everything including earth, solar systems, nebulas, black holes, galaxies etc are contained within. Everything that is observable to us(human) are so far within this universe. So maybe there are more but to human.. there is only 1.

Till today scientifically only one.\n\nGod who created seven universes and the same number of Earths. His command descends between them, that you may know that God is capable of all things, and that God has encompassed all things with His knowledge. (s:Quran 58:8 | 58:12)\n\nQuran claims that currently there are many Earth-like planets.

I highly doubt that there is intelligent life in our solar system there might be organisms on other planets like Mars. But there IS life some where out there. The Earth is infinately small compared to the the universe because the universe is forever expanding. There is no telling how many trillions and trillions of planets have intelligent life roaming around wondering if there is life on other planets just like we are.

It depends on what you mean by earth-like. There have been a few planets that might not be gas giants and are reasonably close to their central stars so they will not be too cold discovered in extrasolar star systems. \n\nI have attached a link to a story about the most recently discovered "earth-like" planet. However, it has a "year" that is only 10 days long, and the surface is over 1000 degrees Fahrenheit, so it is not that much like earth.
