Artist’s conception of the violent stellar flare from Proxima Centauri discovered by scientists in 2019 using nine telescopes across the electromagnetic spectrum, including the Atacama Large ...

Proxima Centauri is a dim star with a magnitude of 11.05, so it's usually too faint to be seen with the naked eye. ... Proxima Centauri b, NASA Exoplanet Catalog, [Accessed 01/20/23], ...

Proxima Centauri (Latin , meaning "next to" or "nearest to") is a red dwarf about 4.24 light-years from the Sun, inside the G-cloud, ... with an apparent magnitude of 11.05.

Proxima Centauri is just 4.2 light years away, ... As such, it sits at magnitude 11—whereas the human eye can see magnitudes up to 6 or 7.

It's also guaranteed, with a minimum mass of 5.8 Earths at its Mars-like distance of 220 million km from Proxima Centauri, to be a cold, puffy world similar to a miniature version of Neptune.

It shines at only magnitude 10.4, appearing as a dim red speck about 2° southwest of the brighter Alpha pair. ... Dubbed Proxima Centauri b, it’s about 25 percent more massive than Earth.

For the closest star, Proxima Centauri, we could detect life on an Earth-like world with only 10 hours of observation. For a Neptune-sized world, the ELT could capture planetary spectra in about ...

On April 29, 2019, the Parkes Radio Telescope in Australia began listing to the radio signals from the Sun’s nearest neighbor, Proxima Centauri, just over 4 lightyears away.

Scientists at an Australian observatory have been studying a radio signal that appears to originate in Proxima Centauri, the star closest to the sun, to see if it may be a sign of intelligent life.

In the case of Proxima Centauri, there was a clear signal of planet b, which takes about 11 days to complete an orbit. That short orbit means it's very close to the star.
