... nearly 200 exoplanets have been discovered orbiting similar type stars in the solar neighbourhood. However out of all...is not alone. Two other planets also circle around the same host star; a so-called “hot Earth” that is about 22 percent larger than...
... sky and is one of the largest visible to the naked eye. Its supergiant status already earmarks it as a variable-type star; a star that regularly brightens and dims with generally predictable frequency. In fact it is one of the most variable...
... around which MOA-2016-BLG-227Lb orbits is classed as an M or K-dwarf star – for comparison our Sun is a G type star and is a main sequence yellow dwarf star. Stars are classified by their spectra (the elements that they absorb) and their temperature...
... in 2010 and subsequent observations revealed that the star hosted a quite complex multi-planet system. HD 3445 is a G0V type star. Our Sun for example is a G2V type star (the 0 represents the hottest stars of a given class, so the Sun is cooler than...
... that given the abundance of CO to H2O in the comet, 2I/Borisov possibly originated around an M-type star - one of the most common stars in our galaxy. As these types of stellar object have low temperatures and luminosities and form late in their...
...It orbits an inflated F-type star known as WASP-76, an ageing and evolved star around 5.3 billion years old. F stars are between 1.0 to...500 K. Scientists suspect that it is these swollen star properties I.e high temperature and large radii, that give...
