The existence of hot Jupiters is puzzling because these gas giant exoplanets orbit very close to their parent stars, often within a few days, which contradicts traditional planet formation theories that suggest such massive planets should form in the colder, outer regions of a protoplanetary disk. Their proximity to the star leads to extreme temperatures, challenging our understanding of planetary atmospheres and their evolution. Additionally, the mechanisms by which these planets migrate inward from their original formation zones remain unclear, raising questions about the dynamics of planetary systems.
What else can I help you with?
What planets are large fast moving and made mostly of gases?
The "exoplanets" known as "Hot Jupiters".
Why are many of the newly detected extrasolar planets called hot Jupiters?
Many newly detected extrasolar planets are called hot Jupiters because they are large, gaseous planets with characteristics similar to Jupiter, but they orbit very close to their host star. This proximity to their star causes them to have high surface temperatures, hence the term "hot."
Why were "hot Jupiters" among the earliest known exoplanets discovered?
Hot Jupiters were among the earliest known exoplanets discovered because they are large gas giants that orbit very close to their parent stars, making them easier to detect using early planet-hunting techniques.

Have you found any other planets bigger than Jupiter?
Yes, there are planets known as "hot Jupiters" that are larger than Jupiter in terms of mass and size. These exoplanets are gas giants like Jupiter but orbit much closer to their host star, resulting in higher temperatures and different atmospheric compositions.
Which statement below does not describe a scientifically reasonable explanation for why the nebular theory failed to predict the existence of the hot Jupiters?
"The theory was not based on accurate observations" does not describe a scientifically reasonable explanation for why the nebular theory failed to predict the existence of hot Jupiters. The actual reason is that hot Jupiters were not part of the original models due to limitations in our understanding of planet formation and migration processes.
What do models suggest make up the clouds on hot Jupiters?
Models suggest that the clouds on hot Jupiters could be composed of minerals like corundum and silicates, as well as exotic compounds such as titanium oxide and aluminum oxide. These clouds may form due to strong winds, vertical mixing, and high temperatures in the atmospheres of hot Jupiters.
How does this planet compare to the hot Jupiters discovered around other stars?
Small & cold.
How might hot Jupiters have gotten so close to the stars they orbit?
Hot Jupiters may have migrated close to their stars due to interactions with the protoplanetary disk during their formation, gravitational interactions with other planets, or tidal forces from the star.
What planets are large fast moving and made mostly of gas?
The exoplanets called "Hot Jupiters."
What planets are large fast moving and made mostly of gases?
The "exoplanets" known as "Hot Jupiters".
How do astronomers explain the orbit of hot jupiters?
Astronomers explain the orbit of hot Jupiters, gas giant exoplanets located close to their stars, through theories of planetary migration. These planets likely formed further from their stars and later migrated inward due to gravitational interactions with the protoplanetary disk or through interactions with other bodies. Tidal forces and the dissipative processes in the disk can also help circularize their orbits. Additionally, some hot Jupiters may have formed in situ through rapid gas accretion in their current locations.
Why are many of the newly detected extrasolar planets called hot Jupiters?
Many newly detected extrasolar planets are called hot Jupiters because they are large, gaseous planets with characteristics similar to Jupiter, but they orbit very close to their host star. This proximity to their star causes them to have high surface temperatures, hence the term "hot."
