I bet you fifty bucks there's a star the size of the moon.

Stars can't be the size of the moon. Then the pressure and temperature in the core is too small to be able to fusion, and then it simply isn't a star. :P

But wow, I'm very surprised that a star can be so small, only a little bit larger than Jupiter. Ofc the mass of it should be many times bigger, since there are planets 4-5 times bigger than Jupiter in other solar systems (I think).

The largest one is TreS-3. It is doubled the size of Jupiter.

Well, you never know. The universe is a huge place. Even if its a one in a trillion chance, it's still possible.

No, because if the stars got much smaller, they would simply turn into huge... Things that would be like planets.
Like a much bigger Jupiter.

There are neutron and quark stars, which are at the size of planets, but they're also only made out of neutrons or quarks I think. But they also aren't normal stars. I guess a star only consisting of neutrons can't fusion, if it's only made of neutrons.

Did you know that if Jupiter had more mass it would be able to have nuclear fusion at its core and thus would be a star?  :o

Ofc I knew that... Jupiter consists mainly of hydrogen, the same as main sequence stars use to fusion...
The diffrence between stars and gas giants is only the mass... In some way.

If it did... Our solar system would be a binary star system  ;D

And we would be incinerated 8)! There would be no nights, except for the time that Jupiter goes behind our sun.

But there is two reasons why we might have night:

R1: Jupiter is too far away from us, so it wouldn't be shining on us, just like the stars that appeared at night.

R2: Jupiter needs more luminousy to shine to Earth.

I guess the effects wouldn't be as dramatic as I stated but still there would be visible climate change and the way animals on Earth live would be effected greatly.

If saturn were a small star like the smallest star known. then our solar system is a binary system.

Impossible, there wouldn't be enough gas and friction to start fusion. The brown dwarf limit is about 11jM and those aren't considered stars. You just lost your 50 bucks.

Or the ESJ angle is low we would have a small night

Sirius B is the size of Earth, I can't see why you can't have a white dwarf near the size of the moon.
