Which star is cooler?

M stars are the coolest stars. They are so cool (2000-3000K) that molecules, including water, carbon monoxide, Vanadium Oxide (used in sunblock) and Titanium oxide (the base of white paint) are visible. These stars are noticeably red: examples are Betelgeuse and Antares.

What are cold stars called?

Y dwarfs are the coldest members of star-like bodies known as brown dwarfs, which are odd objects sometimes known as failed stars. So far, WISE has helped find 100 new brown dwarfs.

What happens if you touch a star?

4 Answers. Surprisingly, yes, for some of them. Small, old stars can be at room temperature ex: WISE 1828+2650, so you could touch the surface without getting burned.

What is the hottest thing in the universe?

The hottest object in the Universe, literally speaking, is the Big Bang. If we go back in time, the Universe gets denser and hotter without a limit. The Big Bang singularity marks the breakdown of Einstein’s theory of gravity, where the density and temperature of matter and radiation diverge to infinite values.

What is the smallest star?

EBLM J0555-57
