BRIGHT PLANET & ASTEROID OCCULTATIONS BY THE MOON FOR 2020


There is probably little new that can be learned from occultations of major planets events in this age of space exploration, but they are still interesting to watch. Photometric records, possibly derived from video recordings, could be used to determine the sizes of asteroids, although timings of occultations of stars by minor planets give more accurate information. - D. Dunham.

2020 proves to be good year for Mars occultations. Below are world maps, showing the events for the planets Venus, Mars, and Jupiter. Mercury, Saturn, Neptune and Uranus are not occulted in 2020. Following the world maps are detailed predictions for the occultations of Mars.

Observers are strongly encouraged to download the free software Occult v4 to generate their own predictions. Occult has a short tutorial listed in the help file to get observers started using the software. Observers can also use their own planetarium type software (e.g. TheSky, SkySafari, Guide, Stellarium, etc), to get approximate times of the events.


The world map is a Mercator projection showing the basic circumstances of an occultation:

Where a line represent a feature of the event is located in the polar regions, remember that the Mercator projection gives rise to serious distortions in polar regions.
