How many Super-Earths were found?
However, interior models of this planet suggest that under most conditions it does not have liquid water. By November 2009, a total of 30 super-Earths had been discovered, 24 of which were first observed by HARPS.
Can we live on Toi 561b?
Given this close proximity, TOI-561b has an average surface temperature of over 3,140 degrees Fahrenheit (1,726 degrees Celsius), which is too hot to host any form of life as we know it, according to a statement from the University of California, Riverside.
What is the youngest planet in the Milky Way?
The hot Jupiter exoplanet V830 Tau b, published in the same issue of the journal Nature as the discovery of K2-33b, is the youngest known exoplanet with an age of around 2 million years (around the time that humans evolved on Earth).
What is the oldest planet in our galaxy?
It is also the first planet found in a globular cluster. The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old….PSR B1620−26 b.

How old is our galaxy?
13.51 billion years
Milky Way/Age
Astronomers have known that the Milky Way is among the oldest of galaxies. The new observations suggest it was indeed one of the first to get under construction. The study puts its age at 13.6 billion years, give or take 800 million years.
Is the sun 10 billion years old?
The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years.
What happened 5 billion years ago on Earth?
About 5 to 6 billion years ago. One of these stars began to run out of Hydrogen fuel. It expanded to a red giant and then collapsed on itself and exploded in a supernova. In this supernova, like billions that have occurred elsewhere in our Universe, all of the other elements were created.
What was the first planet born?
Jupiter
Gas giant’s early existence may explain odd arrangement of planets in the solar system. Jupiter was probably the first planet in the solar system to form, new research suggests. Its existence may have influenced how the planets evolved into the order we see today.
