Are stars Hot or cold?

Are stars Hot or cold?

The color depends on how hot the star is. A red star is the coolest, but still is about 5,000° Fahrenheit! Our sun is yellowish-white and the surface is about 10,000° Fahrenheit. The hottest stars are blue, and can be as hot as 200,000,000° Fahrenheit at their core!

Can we ever visit a star?

Traveling to the stars is very difficult because they are so far away. The nearest star is 25,300,000,000,000 miles (about 39,900,000,000,000 kilometers) away. It is always possible that sometime in the future people may find a way to travel to the stars, but right now we just do not have the technology.

Can stars burn cold?

A star has to be hot enough to sustain fusion* – any colder and they’re no longer stars. So the coldest stars out there are quite cold relative to the sun’s surface temperature of 6,000 Kelvin – but they’re still over 2,000 Kelvin themselves.

What would happen if you touched a neutron star?

Any kind of atom couldn’t keep being atom anymore. So when anything tries to touch neutron star, it would be suck in by gravity and collapse into lump of neutrons and feed their mass into that neutron star. And if it collects enough mass it would collapse into a black hole.

Are all stars white?

The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. The star would therefore appear white — a combination of all colors.

Can we reach sun?

In theory, we could. But the trip is long — the sun is 93 million miles (about 150 million kilometers) away — and we don’t have the technology to safely get astronauts to the sun and back yet. The sun’s surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius). …

What kind of star turns into a black hole?

Neutron stars
What kinds of stars end up as black holes? They are the natural consequence of the evolution of massive stars. Neutron stars have an upper mass limit of 2 to 3 solar masses. A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole.
