I have to coach this event and I know next to nothing about extrasolar systems, however it's a topic I've been meaning to study for a while now so I'm looking forward to it!

Edit: Oh! this is a Question marathon. In that case, explain the difference between Jupiter and a Hot Jupiter

A Hot Jupiter is a large, gaseous planet that orbits in close proximity to a star. Jupiter, on the other hand, orbits at quite a distance from our Sun.

How is the transit method used to discover new exoplanets?

Hey everybody! Just to let you know, this the thread for the Solar System question marathon, where you answer other people's practice questions, and whoever answers gets to ask the next set of questions. Here's how question marathons work. You can get a lot more out of a question marathon if you try to answer others' questions, even if you don't know for sure or you need to use the Internet. It's okay to say "I don't know" as an answer!

On the other hand, if you're simply trying to ask questions you don't have answers for, check out the Solar System thread.

Happy studying!

1. The transit method is a way of discovering planets by measuring the decrease in luminosity when an exoplanet passes by its star to the observer. Using this method, we can use the change in luminosity to determine how close it orbits to its star.
2. For terrestrial planets, some floating materials surrounding the sun clumped together (due to gravity). However, because they were close to the sun, gases were blown away leaving only rocky material left. As for the gaseous planets, the gases were blown farther away from the sun, and gravity pulled the gases into a spherical form. Because the outer planets are mainly made of gases, they are less denser and though many times larger, are not as dense as the terrestrial planets.
3. Keplers Laws:
(1) Planets move in an elliptical orbit with stars as its focus
(2) A planet sweeps out equal areas in its orbit over equal time intervals
(3) The square of a planet's orbit time is proportional to the distance to the star cubed
4. Mini-neptunes are gaseous I believe (though I THINK they have a rocky core) and they're still bigger than Earth by around 2 to 4 times.
5. The moon formed due to a collision between the Earth and a very large asteroid, breaking a chunk of the Earth off, forming a moon. Evidence includes how the Earth's spin and the Moon's orbit have similar orientations, and how the Moon used to be molten.
6. One of the peculiar things about Venus is how it rotates clockwise, and how it takes the longest out of all the planets to complete one rotation. Another thing you may be referencing is how hot Venus is, caused by all the greenhouse gases in its atmosphere, trapping heat.

Question: Which is farther out: the heliosphere or the Oort Cloud?
