In our solar system, the dwarf planets Pluto and Charon orbit each other around a common center of gravity located in the empty space between them. As the only binary planets in our solar system, that makes Pluto and Charon share the title as having the most planets orbiting another planet.
Planet like objects that orbit planets, without them orbiting each other, are called moons.
The title for the planet with most moons, is passed back and forth between Jupiter and Saturn, as new (to us) and ever smaller moons are discovered. Currently, Jupiter holds the title with 63 moons.
Most planets have a solid surface, an atmosphere, and orbit a star. They also vary in size, composition, and distance from their star.
Earth is the home to man
Toutatis is a binary asteroid in our solar system, named after the Celtic god. It is made up of two separate rocky bodies orbiting each other. Toutatis has been closely studied by astronomers, and its complex orbit has been mapped in detail.
Intelligent life may be in it's "very young" stage in the observable Universe. Its 200 billion galaxies show a clear potential to continue on as we see them today for hundreds of billions of years, if not much longer. Because planets and life are so young in our Universe, says Harvard's Dimitar Sasselov, perhaps "the human species are not late comers to the party. We may be among the early ones." That may explain why we see no evidence of "them" and may go a long way to explaining the famous Fermi Paradox, which asks if there's advanced intelligent life in the Universe, where are they? Why haven't we discovered any evidence of their existence?The story of the Universe according to Sasselov in is new study, The Life of Super-Earths, looks like this: generations of stars made enough iron and oxygen, silicon and carbon, and all the other elements from the original hydrogen and helium about 13 billion years ago to be able to form the Earth we live on and the planets the Kepler Mission is discovering today. Stable environments in galaxies that were enriched enough to have planets only became available some nine billion years ago and rocky Earth-like planets and larger super-Earths, only some 7 to 8 billion years ago. And Life had to wait until that time if not later to begin its emergence throughout the Universe. Between 7 and 9 billion years ago, enough heavy elements were available for the complex chemistry needed for life to emerge were in place along with the terrestrial planets with stable environments necessary for chemical concentration. Enrico Fermi argued that given the old age of the Universe and given the large number of stars and planetary systems and the incredibly short timescale it took humans to develop technology that other origins of life and civilizations in the Milky Way could have had a significant head start and should be significantly more advanced than we are. Sasselov concludes that the statistical argument for Fermi's Paradox "holds true only if the timescale for the emergence of life is much shorter than the age of the universe, but not so if the two are comparable." The future for life in the Universe looks excellent, says Sasselov. Planets may be just a tiny fraction of the Universe because of their small size, but there are so many of them that the probability of life grows exponentially. The Universe is passing through the stelliferous era --its peak of star formation--but appears to be still peaking in its formation of planets. There are more stars in the Universe than there are grains of sand on Earth and there are an equal number of planets. There are 200 billion stars in the Milky Way and 90% are small enough and old enough to have planets in orbit. And only 10% of these stars were formed with enough heavy elements to have Earth-like planets with 2% of these --or 100 million super-Earths and Earths-- will orbit within their star's habitable zone. Sasselov's argument in The Life of Super-Earths is compelling. But one has to wonder, however, that if another planet out there in the Milky Way (and billions of galaxies beyond) is only a million years older than Earth, how much more advanced and detectable would their technology be? As Arthur C. Clarke famously wrote, any advanced alien technology would be indistinguishable from magic.
We are very lucky in the environment that we live in. We happen to live in such a narrow band that allows for survival, that the chances of life occurring for us was very slim. We have also evolved to sustain life on Earth, as the climate and our surroundings change, so have we. This process of evolution has allowed us to sustain life to the extent that we do. I am not saying of course that all life has to survive in the narrow bands that we do, as in the Mid Atlantic Ridge there is an abundance of life surrounding the underwater vents where the water pressure is enormous, the water has little, if no oxygen and it is pitch black and life is still able to flourish. According to the latest studies in how life started, there was a chemical reaction in the vents that created the first life single cell life forms. When astronomers and scientists study extrasolar planets, they study their atmosphere with a spectroscope and with an array of scans and rays to see what the atmosphere the extrasolar planets are comprised of. If it is anything remotely close to Earth's, they become interested and study the planet for years to see if life can exist as it does on Earth.
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
No. There are no planets orbiting Earth.The Moon is not a planet.
A planet doesn't "have planets". Anything orbiting a planet is called a moon, or a satellite.
We believe that most stars have planets. The first star PROVABLY detected to have a planet was Gamma Cephei.
8 planets is orbiting the sun
A moon? I don't think a planet orbiting another planet would be called a planet.
No. Planets do not have dwarf planets. A planet-sized object orbiting a larger planet is a moon. Dwarf planets orbit the sun independent of other objects.
The radial velocity method and the transit method have been most successful in discovering massive planets orbiting near their parent stars. The radial velocity method detects planets by measuring the wobble of the star caused by the gravitational pull of the planet, while the transit method detects planets by observing the dip in brightness as the planet passes in front of its star.
As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.
The first planet orbiting the sun is Mercury, and the last planet is Neptune. Mercury is the closest planet to the sun, while Neptune is the farthest.
They all do, its one of the things that is required for a planet to be a planet, directly orbiting the sun.
We call that path the "orbit" of the orbiting body. Note: You would not ever see a planet orbiting another planet. At least, if you did, you would not call them both planets.
