This planet, which is twice the size of Earth and has an important property, has just been discovered

On January 13, 2024, the Haute-Provence Observatory revealed that it had discovered a planet twice the size of Earth. The center will continue its studies to learn the secrets of this unknown star.

HD88986b has been discovered by an observatory in southern France, news that has delighted scientists eager to learn more about the star, reports say. Provence.

“Super-Earth” or “Sub-Neptune”

HD88986b is an exoplanet. “Exoplanets are planets that do not orbit the Sun, but orbit another star. We also talk about… Planets outside the solar system“, NB Future sciences.

“This type of object, which was unknown 15 years ago, is very present, and it is possible that all stars, except the Sun, have it!”, explains Guillaume Hébrard. Experienced in this topic, he is a researcher at the Paris Institute of Astrophysics (IAP) and the Observatory of Hautes-Provence (OHP/CNRS) but is also a co-author of the study led by Nada Haidari (IAP), the same study that revealed the existence of HD88986b.

HD88986b is a “super-Earth” or “sub-Neptune”, orbiting a star in our galaxy. This exoplanet was observed using SOFI+ spectrometer technology installed on it 1 meter telescope 93.

Interesting properties of the observatory

It took the observatory and its teams 25 years to identify and confirm the existence of the star, which is twice the size of the blue planet. The HD88986b is interesting in many respects, not least the fact that (relatively) cold.

With an average temperature of 190 degrees Celsius, HD88986b's atmosphere tells us a lot about its origins and evolution. Furthermore, the researchers note that the star is about 17 times larger than Earth and orbits its star in just 146 days.

In addition, the transformations that the star makes regularly will allow researchers to learn more about its movements as well as its environment.

The first exoplanet was discovered at the Haute-Provence Observatory in 1995. In 2005, 155 were identifieddetails Future sciences.
