- n. The larger and inner of the two planetary satellites of Mars.
Century Dictionary and Cyclopedia
- n. The inner of the two satellites of the planet Mars, discovered by Asaph Hall at Washington, in August, 1877. This extraordinary body revolves in the plane of the equator of Mars, at a distance of only about 3, 700 miles from the surface of the planet, but as it is probably only about five and a half miles in diameter, it would appear only one sixth of the apparent diameter of our moon at the zenith, and on the horizon, owing to the enormous parallax, only about one fourteenth of the same. At the equinoxes it is in eclipse about one fifth of the time, or double that proportion of the time between sunset and sunrise. At the solstices it does not suffer eclipse. It revolves about its primary in 7 hours, 39 minutes, and 14 seconds, and as Mars revolves on its axis in 24 hours, 37 minutes, and 22. 7 seconds, it follows that the satellite appears to an observer on Mars to rise in the west and set in the east, its return to his meridian occurring in 11 hours, 6 minutes, and 23 seconds, but, owing to its close proximity, its velocity will appear to be much greater. At a station on the equator of Mars (where the satellite always passes through the zenith), it will, out of its 11 hours and 6 minutes of period, pass only 3 hours and 20 minutes above the horizon against 7 hours anil 46 minutes below.
