The smallest planet in our solar system 5 years ago was Mercury. Mercury is the smallest planet and the closest to the Sun in our solar system.
There are only eight planets in the Solar System. The celestial body commonly referred to as the "ninth" planet in the Solar System is Pluto, which has been reclassified as a dwarf planet in recent years.
No. It is a planet in another solar system about 500 light-years from Earth in the constellation Cygnus.
The largest planet outside our solar system is currently believed to be a gas giant known as WASP-17b, which is located about 1,000 light-years away from Earth. It is nearly twice the size of Jupiter, the largest planet in our solar system.
The age of a planet is typically determined by the age of the solar system, which is estimated to be around 4.6 billion years old. All planets in our solar system formed around the same time, with Earth being about the same age as the solar system.
In our Solar System - Neptune.Outside our Solar System (so far....) OGLE-2005-BLG-390Lb(at about 21,500 light years)
Makemake, a dwarf planet in our solar system, is estimated to be around 4.5 billion years old, which is the age of the solar system.
That's the age of our Solar System, so you can expect all the planets in our Solar System to have approximately that age.
Neptune, at about 165 Earth years.
4.5 billion years, like the rest of the solar system
That's the age of our Solar System, so you can expect all the planets in our Solar System to have approximately that age.
Yes but keep in mind Pluto is NOT a official planet in the solar system. Neptune was discovered in 1846 and Pluto was discovered in 1930. Pluto is in the solar system, but it is not a major planet, it's called a dwarf planet. A planet which is in the solar system, but not a satellite. So Neptune is the farthest major planet from the sun. It takes 164.79 years for Neptune to orbit the sun lol.
