Astronomers discovered a new star, which proves to be the smallest star ever discovered till date, according to a new article published on July 2017.
An international team of astronomers discovered a tiny red cosmic body, which appeared to be only slightly larger than Saturn. The star, known as EBLM J0555-57Ab, is around 600 light years away from the Earth.
The star was hard to detect, despite its diminutive size and luminosity. Such stars called red dwarves, are believed to have the potential to harboring Earth-sized exoplanets, and they themselves being capable of hosting liquid water on their surfaces.
TRAPPIST-1 was found to be host to seven Earth-sized exoplanets, three of which orbited in the star’s habitable zone.
“This star is smaller, and likely colder than many of the gas giant exoplanets that have so far been identified. While a fascinating feature of stellar physics, it is often harder to measure the size of such dim low-mass stars than for many of the larger planets. Thankfully, we can find these small stars with planet-hunting equipment, when they orbit a larger host star in a binary system. It might sound incredible, but finding a star can at times be harder than finding a planet.” said Alexander Boetticher, lead author of the study.
The newly-discovered red dwarf is similar to TRAPPIST-1, with the only difference being its slightly larger size than Saturn, which has a radius of 72,000 miles (115,872 km), or around 10 times the size of the Earth.
