If it’s a dwarf star, then it could be hard to see, but really massive. Or it might be a really small dwarf star?
I don’t know. I googled around, and I can’t really find any intelligent discussions about it. Although one paranoid site suggested that that’s why FEMA is buying up so much food.
Not enough to go on, and I confess that I haven’t the patience to sit through one of those lengthy videos.
Elenin is a comet smaller than an internatonal airport and its runways.
The Sun is a star some 109 times the diameter of the Earth. A dwarf star is going to be something ont he order of 10 times the diameter of the Earth or larger. A red dwarf star will have a fraction of the mass of the Sun, which is 333,000 times as massive as the Earth. A whicte dwarf star will have many times the mass of the Sun, because it is the remainder of a super-giant star after it blew off its outer atmospheres in a supernova explosion. Elenin is not red, not a star, not a red dwarf star, not a white dwarf star, and not a star of any sort.
Elenin is a comet. Asteroids of its mass pass within the quarter million mile space between the Earth and the Moon quite often with no notice or effect.
