A correction - I mention that neutron stars have 10-29 solar masses. That is actually the mass range of the stars neutron stars originate from. Neutron stars after a supernova are actually about 1-2 solar masses. Sorry for the mistake!

I was confused too when you said that . It happens when we are dealing with things which are too technical Technically they are neutron star just a remnant of star But in my opinion it is not possible because if it is they are close enough that brown dwarf may suck the matter of its star . And it will becomes star and it can be bigger than that. Or crash into it because of both will be so close to each other . So for now it's impossible .

I can't see how a planet could be bigger than it's star. The planet would need to be hydrogen to be less dense than it's star, but still huge and somehow not to collapse onto itself. It would need to be like a semi-condensed gas cloud, which has enough mass to keep it planet-like blob and to resist it's star's radiation, but so evenly distributed and light that it wouldn't start to collapse. I doubt that's possible. What a asteroid crashing into it would do?

Big is a colloquial way to talk about an object of relative high mass and volume. I object that has a high volume is simply called a large object, therefore a Planet can not be Bigger than it's star in terms of mass & volume but it can certainly be larger, in terms of volume.

My first thought before I watched was that a planet bigger than its star by volyme, but not by mass, should be possible. Nice to see that this was where you were going as well. If I am not mistaken most stars in the galaxy are red dwarfs? Quite a few of them could indeed have large gas giants orbiting them. Hopefully we will confirm this in time.

tweezerjam34 the reason for the weird names are that the international astronomical union puts standards on what scientists can name planets which are usually named after the star it orbits and a bunch of numbers and or the telescope that found it with a bunch of numbers. The reason they do this is that scientists have to track thousands of planets and the easiest way to do that is to use names like these

And there must be a few other silly names like that out there so how come you never hear about any of them? Is it just a numbers thing- the chance of one of these “freds” being noteworthy is just too slim? 🤔
