Research offers clues about the timing of Jupiter's formation Dec 09, In the early solar system, when an object got big enough to have appreciable gravity maybe around km in size , heavy stuff like iron, tungsten and molybdenum would sink to the core.
These are atoms that have the same number of protons in their core but different numbers of neutrons. They did this because different isotopes form from different radioactive processes, and these take different amounts of time.
By measuring the relative amounts of isotopes in a sample, they can get a good idea of how old it is and also where in the protoplanetary disk it formed. What they found is that the isotope ratios divide the meteorites into two distinct groups that co-existed in time but were separated in space starting about 1 million years after the planets started forming. Further, these two groups can be separated into ones closer to the Sun than Jupiter and ones farther out.
Something must have separated the material that formed them, and the most likely culprit is Jupiter itself; its gravity literally split the disk in two, carving a gap in it. The meteorites that formed farther out were distinct than the ones closer in. This means Jupiter must have already been massive enough to affect its environment a mere 1 million years after planetary formation began.
Eventually it consumed enough gas around it to grow to its current monstrous mass of more than Earths. So, case closed, right? Well, no. Scientists continue to find new planets each year and even older planets may soon be discovered.
Age: approx. While all of the planets in our solar system are about the same age, it is widely believed that Jupiter formed first, about one million years after the Sun.
Jupiter is the fifth planet from the Sun and is significantly larger than all the other planets in our solar system — it is more than twice as massive as all the other planets combined. Another thing that Jupiter is well-known for is having the most moons, with 79 moons currently confirmed. These four moons are collectively known as the Galilean Satellites and have been well researched due to their interesting features. Age: between 5. For now, it is unclear if any of the seven planets has conditions that can support life.
Recently discovered in , the planet known as Keplerb has been making waves in the scientific community. Keplerb is 60 percent larger in diameter than Earth and is considered a super-Earth exoplanet. Further research is being conducted on the planet and its status as a planet still needs to be confirmed by independent research. At this time, it is uncertain if Keplerb is a rocky planet like Earth and has habitable environments. The next full Moon is the Beaver Moon, and there will be a near-total lunar eclipse.
