They formed farther out like Jupiter but then migrated inward.

Hot Jupiters are giant gas planets that orbit very close to their stars. They are believed to have migrated inward from their original formation locations due to interactions with the protoplanetary disk or other planets in the system. This migration process could have been caused by gravitational interactions or tidal forces, leading to their current close proximity to their stars.

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.
How does this planet compare to the hot Jupiters discovered around other stars?
Small & cold.
What planets are large fast moving and made mostly of gas?
The exoplanets called "Hot Jupiters."
Why are many of the detected extrasolar planets called hot-Jupiters?
Many extrasolar planets are called hot-Jupiters because they are gas giants like Jupiter but much closer to their parent stars, leading to high surface temperatures. Their close proximity to the star results in rapid orbital periods and high levels of irradiation, causing them to be hot compared to Jupiter in our solar system.
How is the planet HD 189733b possible?
Planets like HD 189733 b, sometimes called "hot Jupiters" are one of the most common types of planets to be detected, largely because they are the easiest to detect. Such planets likely form at a great distance from their parent stars, but their orbits decay, bringing them extremely close to their stars. Hot Jupiters often slowly lose their atmospheres.

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 hot is Jupiters core?
Jupiter's core temperature is estimated to be around 20,000°C (36,000°F). This extreme heat is generated by the planet's gravitational compression and the residual heat left over from its formation.
How does this planet compare to the hot Jupiters discovered around other stars?
Small & cold.
What planets are large fast moving and made mostly of gases?
The "exoplanets" known as "Hot Jupiters".
How hot is Jupiters surface?
Jupiter does not have a solid surface, so it does not have a specific temperature at its surface. However, the upper atmosphere of Jupiter can reach temperatures of around 1,340 degrees Celsius (2,444 degrees Fahrenheit).

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."
What is a consequence of the discovery of hot Jupiters for understanding your own Solar System?
The discovery of hot Jupiters has challenged our understanding of planetary formation in our own Solar System. Their presence suggests that the processes that lead to the formation and migration of giant planets may be more complex and varied than previously thought, leading scientists to reevaluate existing models of planetary formation and migration.

What is the climate in the wetland?
Hot and humid according to the location.
