What is the smallest planet in the solar system?
This is due to Mercury being the closest planet to the Sun, ranging from faster than any other in our Solar System and has the shortest year.the what is 80 of 70 how did the fire start
Here on Earth, we to end to not give our measurements of time much thought. But when you consider the fact that increments like a year are entirely relative, dependent on a specific space and place, you begin to see how time really works. Here on Earth, we consider a year to be days. But the actual definition of a year is the time it takes our planet to complete a single orbit around the Sun. So if you were to put yourself in another frame of reference — say, another planet — a year would work out to something else.
July 19, report. The alien world, designated EPIC b, circles its host every four hours and 20 minutes, which makes it the second-shortest orbital period of a planet known to date. The finding was presented in a paper published July 14 on arXiv. The planetary nature of this signal was confirmed by adaptive optics imaging, radial velocity measurements, light curve modeling and analysis of archival images, which excluded the possibility that the star EPIC could be an eclipsing binary. For follow-up observations, the researchers used a variety of instruments, including the Infrared Camera and Spectrograph IRCS on the 8. The newly found planet is slightly smaller than Earth 0.
We have eight planets in our solar system, but until a few years ago, everyone thought there were nine. For many years we considered the little planet at the edge of the galaxy, called Pluto, to be our ninth planet. Pluto was small, but it has its own moons that circle it and because of that, a lot of people considered it to be a planet. That decision put many schools into an uproar, because they had to change everything in all of the science books. Our Milky Way galaxy is very unique in a lot of ways. We have both gas giants and solid planets, planets with rings and some with a lot of moons. As we study other galaxies, we are learning that many solar systems have their largest planets closer to their sun.
The length of a year on any given planet is determined by how long it takes for that planet to make one revolution around the sun. If you had lived on a different planet your whole life, then you would be a different age due to the orbital differences. Mercury : One year on planet Mercury takes just This means that if you are 15 years old on Earth you would be 62 years old in Mercury years. Venus : It takes If you are 15 years old on Earth, this would make you 24 years old in Venus years.

Risinger skysurvey. For the very first time, they have been able to figure out how long the day is for a distant alien world, and this massive planet is setting records with the shortest day of any planet we know about. Back in mid-November of , astronomers using the Very Large Telescope, at the ESO in northern Chile, discovered a massive alien world orbiting the bright blue star Beta Pictoris, located roughly 63 light years away from Earth. Studies of this 'exoplanet' - named Beta Pictoris b - have yielded estimates of its size and mass 65 per cent larger than Jupiter and between 4 and 11 times Jupiter's mass , the length of its year around 20 Earth years , and it was even one of the very first exoplanets that astronomers were able to directly image as opposed to just seeing indirect evidence of it. One of the latest studies, using the very same Very Large Telescope VLT have produced an even more amazing tidbit of information about this world: the length of its day. If someone were able to stand on the 'surface' of this massive gas-giant planet, they would see Beta Pictoris rise every 8 hours. That means that the planet spins at a dizzying rate of over , kilometers per hour, which is over twice as fast as Jupiter, and nearly 60 times faster than Earth.
Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. This brings up the question of how we define the time intervals we measure. What is a day? What is a year? The earth is in motion. Actually, several different motions all at once.
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of It is named after the Roman deity Mercury , the messenger of the gods. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or eastern horizon before sunrise , usually in twilight. At this time, it may appear as a bright star-like object, but is often far more difficult to observe than Venus. The planet telescopically displays the complete range of phases , similar to Venus and the Moon, as it moves in its inner orbit relative to Earth, which recurs over its synodic period of approximately every days.
Mercury has the shortest year in the solar system. It takes 88 days to complete one revolution around the sun. Followed by Venus that takes

Mercury is an extreme planet in several respects. Because of its nearness to the Sun —its average orbital distance is 58 million km 36 million miles —it has the shortest year a revolution period of 88 days and receives the most intense solar radiation of all the planets. In addition, Mercury is unusually dense. It takes about days for successive elongations —i. Even above the atmosphere, orbiting observatories such as the Hubble Space Telescope are restricted by the high sensitivity of their instruments from pointing as close to the Sun as would be required for observing Mercury.
