This week NASA’s Unexplained Files looks at why Jupiter is so hot and examines how NASA helped with a … The term “hot” in this context means that the planet is expected to be much hotter than our own Jupiter by virtue of the fact that the planet is much closer to the host star than our Jupiter … Jupiter lies out beyond Mars, but it is not as cold as scientists expected. Jupiter is one of the brightest objects visible to the naked eye in the night sky, and has been known to ancient civilizations since before recorded history. Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. The ultra-hot Jupiter, known as KELT-9b, is approximately three times more massive than our own Jupiter and orbits star some 670 light-years away. Its gravity likely prevented the … Jupiter is significant not only for its size but also for its location in our solar system, far from the Sun. Therefore, as one side of the hot Jupiter broils, the planet's far side features much cooler temperatures. It is high horizontal winds — in excess of 300 kilometers per hour — that cause the zones to spread out planet-wide. Scientists have also studied the weather on hot Jupiter HAT-P-2b — a planet in an eccentric orbit around its sun (it only takes 5 days or so to complete one orbit). Astronomers believe this happens through a process called core accretion. They typically have temperatures of a thousand to several thousand … Because it orbits at slightly more than 5 AU (astronomical units the distance between the Earth and the Sun is 1 AU), there is plenty of room in the inner part of our Solar System to accommodate a range of smaller planets. A new look at a Jupiter-size planet orbiting extremely close to its parent star seems to defy the leading hypothesis for how these "hot Jupiters" arrive at their tight orbits. So-called ”hot Jupiters” are everywhere but our solar system. Why do colorful cloud bands encircle Jupiter? In our solar system, Jupiter can eat up any asteroid or comet that ventures near, earning the nickname “vacuum cleaner of the solar system.” The asteroid belt in between the orbits of Mars and Jupiter is another example of the gas giant’s influence. Hot Jupiters migrate in from the outer regions of the solar system, taking out any small planets in their way. What causes these strong winds remains a topic of research. If our solar system had a hot Jupiter, we wouldn't be here to see it. Jupiter’s top atmospheric layer is divided into light zones and dark belts that go all the way around the giant planet. To make a hot Jupiter, first you must form a gas giant. Jupiter’s journey. (Our Jupiter has a mass and radius of 317.828 and 10.9733 times the corresponding quantities for Earth, respectively.) “So, the atmospheres of hot jupiters are very exotic, by solar system standards. They're probably pretty rare; the current list contains a lot of them, because for a few years "hot Jupiter" type systems were the only ones that could be detected.
