NGTS-1b is a confirmed hot Jupiter-sized extrasolar planet orbiting NGTS-1, a red dwarf star about half the mass and radius of the Sun, every 2.65 days. The NGTS-1 system is about 716 light-years from Earth in the Columba constellation.
The exoplanet, NGTS-1b, was discovered by the Next-Generation Transit Survey. Daniel Bayliss, of the University of Warwick, and lead author of the study describing the discovery of NGTS-1b, stated, "The discovery of NGTS-1b was a complete surprise to usâÂÂsuch massive planets were not thought to exist around such small starsâÂÂimportantly, our challenge now is to find out how common these types of planets are in the Galaxy, and with the new Next-Generation Transit Survey facility we are well-placed to do just that."
NGTS-1b is a hot Jupiter-sized gas giant exoplanet that has a mass of 0.812 M<sub>J</sub> and a radius of 1.33 R<sub>J</sub>, where M<sub>J</sub> and R<sub>J</sub> are the mass and radius of Jupiter.
The planet orbits an M0.5 dwarf star about half the mass () and radius () of the Sun.
NGTS-1b orbits about from the host star every 2.6473 Earth-days.
