Youngest planet in the solar system

How old are the planets in the Solar System?

The planets in the Solar system are 4.5 billion years old approximately. All of them formed around the same time with some slight differences. The following table lists the age of the planets in the solar system to the best approximation that we have for each. It is important to note that these are very rough estimations.

Could this planet be the youngest ever discovered?

And if the host star’s estimated age of just 1.6 million years holds true, this exoplanet could be one of the youngest ever detected. Further research is needed, and astrophysicists hope that upcoming observations with the James Webb Space Telescope will confirm the planet’s presence.

What is the youngest fully formed exoplanet ever found?

The planet K2-33b, discovered during the Kepler space telescope's K2 mission, is the youngest fully formed exoplanet ever found. The Neptune-size planet is 5 million to 10 million years old. (For comparison, Earth is 4.5 billion years old.)(Image credit: NASA/JPL-Caltech)

What is the eldest planet in the Solar System?

The eldest planet is Jupiter, which was formed shortly after the creation of the Solar system. We know the age of the planets thanks to the radioactive decay of elements found on meteorites. Many mysteries remain about the origin of our Solar System, but we have a good idea of how and when it was formed along with the asteroids and planets in it.

Why is the Moon the youngest planet in Earth's history?

The reason that these unlikely worlds emerge as the youngest has to do with the fact that they both experienced massive collisions. The primordial Earth likely collided with Theia, a Mars-sized planetoid, and from that dramatic event, the Moon formed. That happened around 4.5 billion years ago. It took the Moon about 200 million years to solidify.

Is LkCa 15 B the youngest planet ever found?

Images have revealed that the forming planet sits inside a wide gap between the young parent star and an outer disk of dust. “LkCa 15 b is the youngest planet ever found, about five times younger than the previous record holder,” said Adam Kraus from the University of Hawaii. “This young gas giant is being built out of the dust and gas.
