What is the oldest known planet in the universe?
The exoplanet known as PSR B12620-26 b is the oldest known planet in the universe, with an estimated age of about 13 billion years.
How old is the oldest Earth like planet?
13 billion years
NASA’s Hubble Space Telescope precisely measured the mass of the oldest known planet in our Milky Way galaxy. 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.
What did astronomers initially think that PSR B1620-26 b was?
Before astronomers determined that PSR B1620-26 b was a planet, they went back and forth over its identity and thought that it could possibly be an object between the size of a planet and a small star.
How far away is PSR B1620-26?

What is the youngest planet?
K2-33b
It’s at least five billion years younger than Earth. NASA scientists just announced the discovery of the youngest planet every found in the universe. The planet is named K2-33b, and closely orbits a new star — which makes the planet very hot.

Why is studying dark energy important?
New research on dark energy is helping scientists understand the potential fate of the Universe. Dark energy makes up about 70 percent of the current content of the Universe and thus holds the ultimate fate of our Universe.
What was the first discovered exoplanet?
pulsar PSR B1257+12
In 1992, astronomers discovered the first exoplanet, or planet outside our solar system. But it didn’t come in any form they’d really anticipated. The first exoplanets ever discovered were found orbiting the pulsar PSR B1257+12. It took years for astronomers to find exoplanets around sun-like stars.
What is the Sun’s name?
sol
The Sun has been called by many names. The Latin word for Sun is “sol,” which is the main adjective for all things Sun-related: solar. Helios, the Sun god in ancient Greek mythology, lends his name to many Sun-related terms as well, such as heliosphere and helioseismology.
