Latitude varies from â90Â° to 90Â°. The latitude of the Equator is 0Â°; the latitude of the South Pole is â90Â°; the latitude of the North Pole is 90Â°. Positive latitude values correspond to the geographic locations north of the Equator (abbrev.
If youâre on Mars, or at least work by a Mars clock, you have to figure out how to put up with the exhausting challenge of those extra 40 minutes. To be exact, the Martian day is 24 hours, 39 minutes, and 35 seconds long, a length of day that doesnât coincide with the human bodyâs natural rhythms. Scientists, Mars rover drivers, and everyone else in the space community call the Martian day a âsolâ to differentiate it from an Earth day.
Because its orbital eccentricity is greater than that of Earth, the length of day varies from the average by a greater amount than that of Earth, and hence its equation of time shows greater variation than that of Earth: on Mars, the Sun can run 50 minutes slower or 40 minutes faster than a Martian clock (on Earth, the corresponding figures are 14m 22s slower and 16m 23s faster).
