An 'occultation' of Mars is coming on the night of Dec. 7, 2022. How to view the rare event with your naked eye. Or even better, with a telescope.
If a planet rotates prograde, and the sidereal day exactly equals the orbital period, then the formula above gives an infinitely long solar day (division by zero). This is the case for a planet in synchronous rotation ; in the case of zero eccentricity, one hemisphere experiences eternal day, the other eternal night, with a "twilight belt ...
Mars and the moon will be about four degrees apart on Wednesday evening. The conjunction should be visible around 10 p.m. local time on Wednesday, November 20, according to The Weather Channel ...
The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year.The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day, and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.9711 days on Earth).
