Some M stars are excellent candidates to search for terrestrial worlds that lie in their habitable zone (liquid water orbital distance range). Proxima Centauri, for instance, is a cool red dwarf star about 4.2 light-years from our Sun, which harbors a planet in its habitable zone. This exop...
The extra-solar planet known as Proxima b has occupied a special place in the public mind ever since its existence was announced inAugust of 2016. As the closest exoplanet to our Solar System, its discovery has raised questions about the possibility of exploring it in the not-too-distant fu...
A common question when looking at the Solar System and Earth’s place in the grand scheme of it is “which planet is closest to Earth?” Aside from satisfying a person’s general curiosity, this question is also of great importance when it comes to space exploration. And as humanity contem...
Scientists say they discovered an earth-like planet orbiting the star closest to our planet other than the sun. It is the closest planet ever found outside our solar system that could support life as we know it. This planet is just 4.2 light years away from us. It is so close that spa...

A fourth planet, Gliese 581e, was spotted in 2009. This planet was the closest planet to the star, orbiting at a distance of just 2.6 million miles (4.2 million km) every 3.2 days, and its mass is about 2.5 times that of Earth. Not one of these planets has a direct analog in the...
Planet formation in the habitable zone of alpha Centauri B Recent studies have shown that alpha Centauri B might be, from an observational point of view, an ideal candidate for the detection of an Earth-like planet... P Thebault,F Marzari,H Scholl - 《Monthly Notices of the Royal Astronomi...
TRAPPIST-1 b is the closest planet to the M-dwarf star of the system, and it receives four times as much radiation as Earth receives from the Sun. This relatively large amount of stellar heating suggests that its thermal emission may be measurable. Here we present photometric secondary ...
Friday, January 10, 2025: The BepiColombo spacecraft has made its sixth and final flyby of the closest planet to the sun, Mercury, capturing some incredible images of the tiny world. The photos offer tantalizing hints about some of the mysteries BepiColombo will investigate when it moves into...
