Mars in 1951: a year between two loops

692 days separate the end of one Mars retrograde from the start of the next, and 1951 falls entirely inside that stretch. Mars turns back once every 779.94 days — longer than a calendar year — and each loop is over in weeks, so now and then a whole year passes between two of them.

The loops themselves are on the 1950 and 1952 pages.

Computed from the actual motion

The nearest Mars retrogrades either side of 1951

Previous

1950 Ended May 3, 1950 after 80 days, moving back 19.03° through the zodiac.

Next

1952 Begins March 25, 1952 and runs 77 days.

Gap across 1951

1.9 years between the two — long enough for a whole calendar year to fall inside it with nothing to report.

Both dates are computed from the planet’s apparent motion, not taken from a table. A retrograde begins the moment its daily movement against the stars turns negative, and that moment is findable to the hour.

Mars through the zodiac in 1951

Every sign Mars occupies during 1951, with the dates it enters and leaves. A sign that appears twice means the planet backed into the previous sign during a retrograde and crossed again.
