How does this relate to the formation of Jupiter?

Currently nobody knows. There are two possible options being pursued - core accretion and disk instability...

But that *is* the answer to the question you have asked.

# How was Jupiter formed

(Asked by: username_0 on 2017-12-12)

Two days ago I went to a mathematics conference where there was a paper presented on Jupiter's formation via the disk-instability model.

I know that there are two different theories for the formation of the planets. One of them is the **Core accretion** model and the other one is the **disk-instability** model. I also tried to read this paper on planetary formation in which they said 161 planets were put on to test. 90% followed Core accretion model and rest of them followed the later model. Did not say anything explicit about Jupiter.

Jupiter is too close to the Sun to follow the Disk-Instability model (I am not sure completely).

Now I want to know which model Jupiter follows for its formation.
