Planets
Sunsets on other planets appear different because of the differences in the distance of the planet from the Sun, as well as different atmospheric compositions.
On Mars, the Sun appears only about two-thirds of the size that it appears in a sunset seen from Earth, because Mars is farther from the Sun than the Earth is. Although Mars lacks oxygen and nitrogen in the atmosphere, it is covered in red dust frequently hoisted into the atmosphere by fast but thin winds. At least some Martian days are capped by a sunset significantly longer and redder than typical on Earth. One study reported that for up to two hours after twilight, sunlight continued to reflect off Martian dust high in the atmosphere, casting a diffuse glow.

Famous quotes containing the word planets:
“I would sell my life to avoid
the pain that begins in the crib
with its bars or perhaps
with your first breath
when the planets drill
your future into you....”
—Anne Sexton (1928–1974)
“Why are all these dolls falling out of the sky?
Was there a father?
Or have the planets cut holes in their nets
and let our childhood out,
or are we the dolls themselves,
born but never fed?”
—Anne Sexton (1928–1974)
“Perhaps when distant people on other planets pick up some wave-length of ours all they hear is a continuous scream.”
—Iris Murdoch (b. 1919)
