What color would our sky be if Earth's sun was a red dwarf?

Question

Earth's sun is white, but we see it as yellow due to our atmosphere, and the sky appears blue due to light scattering. But what color would our sky be if the sun was a red dwarf? Would it appear red, or orange?

Answer 1

If the sun was a deep red dwarf, the sky would appear much darker, and look more like we don't have an atmosphere. Brighter stars would be visible even in daytime. Whatever color that can be seen in the sky, most noticeably in that part of the sky where the sun is, you'd see orange-yellow. Further away from where the sun is, you'd actually see some faint green. The ground will remain bright, even though reddish in appearance, and shadows would be sharper and darker. And it would be very cold.

Answer 2

If the Sun were a red dwarf, we most likely would have evolved with different vision apparatus - sensitive further into the infrared and less into the blue. So we would still think of sunlight as "white". In any case, whatever the peak wavelength of the sun, the atmosphere will scatter shorter wavelengths more than longer ones, and the color of the sky will be towards the blue end of the spectrum.

Answer 3

Probably yellow-ish, since a red dwarf peaks in the red, but still lets out other colors to lesser degrees. But if the sun were becoming a red dwarf, the sky color would be the least of our problems - the sun would be enveloping the Earth.

Answer 4

if our sun were red, our sky would still be blue.

if the term you meant to use was red GIANT, the Earth would no longer exist because the size of the sun would be larger than the Earth's orbit (the location of where the Earth would have been will be inside the sun).

Answer 5

WHAT??? what earth? :) as you may be knowing that the earth's position in the hostile solar system has been guaranteed by number of forces, call 'em infinite combinations, one of them for example is Jupiter, without it, we would have gotten huge comets and asteroids at the time of infancy, and you would not be askin' and I would not be answerin' questions. In fact, it would have been a Wish of God that someday, we communicate.

Answer 6

it is going to nonetheless be blue... bt in case of a pink dwarf the sky will be darker than what we are used to... and in case of a blue superstar the sky will be brighter because the solar will b hotter than what it is now it is yellow dwarf...

Answer 7

red + black = purple
