C/1702 H1, also known as the "Comet of 1702", is a comet discovered by Francesco Bianchini and Giacomo Filippo Maraldi in Rome, then part of the Papal States, on April 20, 1702.[2]
1702 apparition
[edit]Bianchini and Maraldi discovered the comet on April 20, 1702. The comet was a short distance above the horizon and was said to resemble a "nebulous star".
The comet was independently discovered by Maria Margaretha Kirch (Berlin, Prussia) on April 21,[3] and by Philippe de La Hire (Paris, France) on April 24.
The last observation of the comet was made by Bianchini and Maraldi on May 5, 1702.
Orbit
[edit]Very similar parabolic orbits were computed for C/1702 H1 by Nicolas Louis de Lacaille (1761) and Johann Karl Burckhardt (1807).
