Written and fact-checked by The Editors of Encyclopaedia BritannicaThe characteristic temperature on Mars in the lower atmosphere is about 200 kelvins (K; −100 °F, −70 °C), which is generally colder than the average daytime surface temperature of 250 K (−10 °F, −20 °C). ...
The temperature on Mars is relatively low, averaging about minus 80 degrees Fahrenheit (minus 60 degrees Celsius).
The rover starts work during the afternoon when the temperature has hit its highest so it can store energy for its night shift. But just 30 percent of solar energy can be transferred into electricity. Another power innovation is a chemical called N-undecane, which will absorb the...
First quarter moons always rise around mid-day and set around midnight, so they are also visible in the afternoon daytime sky. The evenings surrounding the first quarter are the best ones for seeing the lunar terrain when it is dramatically lit by low-angled sunlight, especially along the ...
Once a year, an astronomical alignment ushers in this seasonal change. The solstice is celebrated across the world—and shrouded in myth.
on the eccentricity of its orbit. In summer, when it is at its closest approach to the sun, the daytime temperature can reach 465 degrees Celsius (870 degrees Fahrenheit). At night, the temperature can drop to -184 degrees Celsius (-363 degrees Fahrenheit). This happens because the planet...
While the idea of living on Mars is great, the reality does not look as good. Mars does not have a friendly atmosphere for humans. There is very little oxygen there. And because of its distance from the sun, it is also very cold. The temperature on Mars can be -62 degrees on averag...

This daytime infrared image was collected Aug. 13, 2003 during southern spring. The upper part of the image shows the relatively young volcanic flows from Arsia Mons, while the bottom exhibits the flow front texture of older flows. The older flows are most likely also from Arsia Mons ...
daytime temperature, astronomers suspect ice is located deep in its craters. These craters were the result of massive meteorites striking the surface throughout Mercury's billions of years in existence. Mercury is slightly smaller than the Earth's moon and is the smallest planet in this solar ...
