Mars in 1902: a year between two loops

685 days separate the end of one Mars retrograde from the start of the next, and 1902 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 run-up to the next loop starts before the year is out: the pre-retrograde shadow opens on December 14, the day Mars first reaches the degree it will later retreat to.

The loops themselves are on the 1901 and 1903 pages.

Computed from the actual motion

The nearest Mars retrogrades either side of 1902

Previous

1901 Ended April 4, 1901 after 81 days, moving back 19.48° through the zodiac.

Next

1903 Begins February 18, 1903 and runs 80 days.

Gap across 1902

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 1902

Every sign Mars occupies during 1902, 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.
