Hot Jupiter WASP-174b - one of the exoplanets - has been studied by researchers. She was called one of the least dense.
The study is about hot Jupiter around the star WASP-174. It is a yellow-white dwarf with a mass of about 1.25 solar masses and a diameter of 1.35 solar stars (about 2.2 billion years old star).
Earlier, a giant planet was noticed near this star, the mass of which is approximately 1.3 masses of Jupiter. As for the diameter, it could not be determined. Presumably, it could be 70-170% of the diameter of Jupiter. Scientists called this planet WASP-174b.
A new study allowed a more detailed study of a space object. To do this, scientists used ground-based telescopes, as well as the TESS space telescope. It was determined that the diameter of the exoplanet exceeds the diameter of Jupiter by 1.4 times. Its density is 0.135 grams per cubic centimeter. This is one of the least dense exoplanets.
The features of the WASP-174b can make it an excellent subject for research. Since it is larger in comparison with other exoplanets, it is easier to see.
