Why is our Jupiter not a “hot Jupiter”? It is likely that in our system the nebular gas cleared out before it could have much migratory effect on the planet . How much brighter is a Sun-like star than the reflected light from a planet orbiting around it? big planets in edge-on orbits around small stars.
How does a hot Jupiter differ from Jupiter quizlet?
How does a hot Jupiter differ from Jupiter? It’s much closer to its star . ... The nebular theory predicts that jovian planets should only form at much larger distances from their stars.
Why is the discovery of hot Jupiters surprising?
Hot Jupiters like 51 Pegasi b were the first type of planet discovered around sun-like stars. What led to their discovery? It occurred after astronomers started using a technique called the radial velocity method to look for extrasolar planets . ... It was a surprising but fortuitous discovery.
What do we mean by a hot Jupiter?
Hot Jupiters are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (P < 10 days). The close proximity to their stars and high surface-atmosphere temperatures resulted in the moniker “hot Jupiters”.
What defines a hot Jupiter planet quizlet?
*Hot Jupiters are jovian planets that are very close to their stars . Their discovery came as a surprise to scientists because in our solar system jovian planets are only found far from the Sun. ... Once the hot Jupiters were discovered, it was natural that the nebular theory would need to be extended to accomodate them.
What role has Jupiter played in Earth’s habitability?
What role has Jupiter played in Earth’s habitability? Jupiter’s gravitational effects helped clear the inner solar system of objects that could cause impacts . What is the common property that distinguishes stars on the main sequence of the H-R diagram from other stars on the diagram?
What’s the best explanation for the location of hot Jupiters?
What’s the best explanation for the location of hot Jupiters? They formed farther out like Jupiter but then migrated inward.
How hot is Jupiter at night?
Jupiter – minus 162°F (-108°C)
Is Jupiter hotter than the sun?
The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit). The temperature near the planet’s center is much, much hotter. The core temperature may be about 24,000 degrees Celsius (43,000 degrees Fahrenheit). That’s hotter than the surface of the sun !
Is it hot on Jupiter?
It’s really hot inside Jupiter ! 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. Jupiter is made up almost entirely of hydrogen and helium. On the surface of Jupiter–and on Earth–those elements are gases.
Why Jupiter is so hot?
An artist’s impression of Jupiter with the four Galilean moons. ... Using data from the Keck Observatory in Hawaii, the researchers created the most-detailed yet global heat map of the planet’s upper atmosphere and confirmed that Jupiter’s powerful aurorae are responsible for heating the planet .
Where is hot Jupiter?
Hot Jupiters are giant planets that orbit very close to their host star , typically less than one-tenth the distance between Earth and the Sun. They are found in about 1 percent of systems.
Is Jupiter in our solar system?
Jupiter is the biggest planet in our solar system . ... Jupiter is covered in swirling cloud stripes. It has big storms like the Great Red Spot, which has been going for hundreds of years. Jupiter is a gas giant and doesn’t have a solid surface, but it may have a solid inner core about the size of Earth.
What are the three major methods used to detect extrasolar planets indirectly?
Indirect observations (such as the Doppler technique, transits, and eclipses ) are much more commonly used when searching for exoplanets. The Doppler technique is a good method for discovering exoplanets. It uses the Doppler effect to analyze the motion and properties of the star and planet.
Why is Jupiter denser than Saturn Why is Jupiter denser than Saturn?
Jupiter is denser than Saturn because it 3 times more massive . Gravity makes it denser. Jovian planets are not quite spherical because of their rapid rotation.
Which planet search technique is currently best suited to finding Earth like planets?
The most successful search method used to date is called the transit method . If a planet passes directly between a star and the observer, it blocks out a tiny portion of the star’s light.
