What is the difference between brown dwarfs and Jupiter?

Answer 1

Jupiter is a planet, brown dwarfs are too big to be planets.

Something that is too large to be a planet but too small to be a star is known as a brown dwarf.

Brown dwarfs are smaller than 0.08 solar masses, which is the lower mass limit for fusion reactions to initiate, and have more than twice the mass of Jupiter.

Only in 1995 was the existence of brown dwarfs confirmed; they are thought to be numerous, possibly even more so than stars, and are identified by the infrared radiation they emit from dust clouds.

Jupiter is a planet in our solar system that is mostly made of gas and does not have the mass or conditions to go through nuclear fusion. Brown dwarfs, on the other hand, are substellar objects that are not massive enough to sustain hydrogen-1 fusion reactions in their cores.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
