Qatar-3b is a hot Jupiter orbiting the star Qatar-3 located in the Andromeda constellation.[2] It orbits its star every 2.5 days. It was discovered in 2016 by the Qatar Exoplanet Survey(QES).[3][1]
Discovery[edit]
This planet was discovered by QES along with Qatar-4b and Qatar-5b. The light curves of the planet's respective host stars have been observed as well during the survey, along with their stellar properties[4]
Properties[edit]
Orbit[edit]
This planet is another typical hot Jupiter. It orbits very close to its star with a period of 2 days, 12 hours, 11 minutes, and 24 seconds.[5] This corresponds with an orbital distance of about 0.04 AU, which is 10 times closer to its star than Mercury is to the Sun. With an eccentricity of 0, this suggests that Qatar-3b is on a perfectly circular orbit.
Physical Properties[edit]
Qatar-3b is a massive planet, with 4.31 times the mass of Jupiter, and has a similar radius to the latter. With a density if 4.0 g cm−3, this is one of the densest planets discovered. With an effective temperature of 1,681 K, it is a scorching planet.
