It was a surprising but fortuitous discovery. First of all, hot Jupiters rarely have moons. The reddish brown and white stripes of Jupiter are made up of swirling clouds. The 'hot Jupiter' planet was found orbiting the star V830 Tau, as seen in this artist's conception. Planets like these are referred to as "Hot Jupiters.” Some of the most common planets in other solar systems are some of the strangest: extremely hot, Jupiter-sized planets that orbit at insane rates around their host planets. Ultra-hot Jupiters are a new class of exoplanets that astronomers are increasingly finding scattered throughout the cosmos. Although hot Jupiters are unlikely places to find life, they could be orbited by moons that would have pleasant, Earth-like temperatures. It was a very happy surprise to find hot Jupiters, which produce an even larger signal, on a shorter timescale. No one knows exactly how hot, but scientists think it could be about 43,000°F (24,000°C) near Jupiter's center, or core. 5-9 This is true even for hot Jupiters having periods longer than a day, such as WASP-12b, mentioned in the above quotation. But unlike Jupiter, which is five times as far from the Sun as Earth and orbits the Sun in 12 years, 51 Peg is twenty times closer to its star than Earth is to the Sun and orbits its star every 4 days.
Astronomers have found far more planets like this in the cluster than expected. In fact, given what was known about the formation of giant planets, the discovery of the first hot Jupiter in 1995 was a big surprise, Hébrard said.
This artist’s impression shows a hot-Jupiter orbiting close to one of the stars in the star cluster Messier 67. It is unlikely. 5 Some of these planets have undergone measurable decreases in the lengths of their orbital periods. Based on what we know about our own solar system, the discovery of hot Jupiters came as a surprise to scientists because these planets are _____.
The real haul has been in gas giants, especially “hot Jupiters.” These are behemoth worlds that orbit close to their parent stars, blocking a fraction of the star’s light when it transits in front. Observations of hot Jupiter “mini-eclipses” have yielded hundreds of discoveries. In a new study, scientists described such an exoplanet that is so ridiculously hot that even molecules in its atmosphere are torn to shreds. Paul Sutter explains.

This artist’s impression shows a hot-Jupiter orbiting close to one of the stars in the star cluster Messier 67. 22. so close to their stars Our modern theory of solar system formation—the nebular theory—successfully accounts for all the major features of our own solar system. However, astronomers have detected several hot Jupiters that apparently have already started their “death spirals” into their host stars. What do hot Jupiters mean for our understanding our own Solar System? Therefore, potential moons are likely to get
