[9] However, the non-periodic comet C/1925 F1 (Shajn-Comas Solá; also known as Comet 1925 VI or Comet 1925a) was co-discovered by her husband rather ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
These are lists of planets.A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk.
Helin is credited by the Minor Planet Center with the discovery or co-discovered of more than 900 numbered minor planets, including the first two Aten asteroids: 2062 Aten and 2100 Ra-Shalom, which gave rise to this new orbital group of near-Earth objects. [1] [10] She also discovered:

Its orbit revealed that it was a new planet, Uranus, the first ever discovered telescopically. [20] Giuseppe Piazzi discovered Ceres in 1801, a small world between Mars and Jupiter. It was considered another planet, but after subsequent discoveries of other small worlds in the same region, it and the others were eventually reclassified as ...
