What is the Oldest Planet in the Universe? Methuselah (PSR B1620-26 b) is the oldest planet in the universe. At least the oldest planet that we know of so far. It''s about 12.7 billion years old, making it 2.8 times older than our solar system. This ancient planet shows us how long some planetary systems can last.
It is 4.566 billion years old which means it formed only 2 million years after the Solar system. All the planets in the Solar system have more or less the same age, 4.5 billion years. The eldest planet is Jupiter, which was formed shortly after the creation of the Solar system.

Jupiter is the largest planet in our solar system. If Jupiter was a hollow shell, 1,000 Earths could fit inside. Jupiter also is the oldest planet, forming from the dust and gases left over from the Sun''s formation 4.5 billion years ago.

PSR B1620-26 b is an exoplanet located approximately 12,400 light-years from Earth in the constellation of Scorpius bears the unofficial nicknames "Methuselah" and "the Genesis planet" (named after the Biblical character Methuselah, who, according to the Bible, lived to be the oldest person) due to its extreme age.The planet is in a circumbinary orbit around the two stars of
Jan 27, 2015· The astronomers assume that, as in our solar system, the planets formed quickly after the star did. "By the time the Earth formed, the planets in this system were already older than our planet is today," Chaplin says. The immense age of the Kepler-444 system suggests that Earth-class planets could have formed very early in the life of the universe.

At an estimated age of 13 billion years, the planet is more than twice as old as Earth''s 4.5 billion years. It''s about as old as a planet can be. It formed around a young, sun-like star barely 1 billion years after our universe''s birth. NASA''s Hubble Space Telescope precisely measured the mass of the oldest known planet in our Milky Way galaxy.

Let''s look at the mean temperature of the Sun, and the planets in our solar system. The mean temperature is the average temperature over the surface of the rocky planets: Mercury, Venus, Earth, and Mars. Dwarf planet Pluto also has a solid surface. But since the gas giants don''t have a surface, the mean is the average temperature at what
Introduction. You might think that all the Planets in the The Solar System were born at the same time. Actually, you''d be wrong. All the planets didn''t start at the same time. Scientists believe that the oldest planet in the Solar System is Jupiter. Jupiter is the largest planet in the Solar System and is famous for having the large red spot which is an on-going storm.
