. She predicted the return of Halley's Comet, calculated the timing of a solar eclipse
Solar eclipse
As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially blocks the Sun as viewed from a location on Earth. This can happen only during a new moon, when the Sun and the Moon are in conjunction as seen from Earth. At least...

A clockmaker is an artisan who makes and repairs clocks. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks. Modern clockmakers may be employed by jewellers, antique shops, and places devoted strictly to repairing clocks and watches...

. Nicole Lepaute constructed a clock with an astronomical function together with her spouse. The clock was constructed on her suggestion, and she also participated in its construction. The clock was presented to the French Academy of Science in 1753, were it was inspected and approved by Jérôme Lalande

Jupiter
Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. Jupiter is classified as a gas giant along with Saturn,...

 of the Halley's comet. In november 1758, the team presented their conclusion that the comet was to arive in 13 April 1759. They were almost correct, as the comet arived the 13 March 1759. Clairault did not recognize her work at all in his work, which upset Lalande. Jérôme Lalande acknowledged her help in an article.

In 1759, she was again a part of Jérôme Lalande's team and worked with him to calculate the Ephemeris

. It is not documented what should be contributed to her personally, but in 1761, she was acknowledged by being inducted as an honorary member of the distinguished Scientific Academy of Beziéres.

In 1762 Lepaute calculated the exact time of a coming solar eclipse
Solar eclipse
As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially blocks the Sun as viewed from a location on Earth. This can happen only during a new moon, when the Sun and the Moon are in conjunction as seen from Earth. At least...

Europe

Comprising the westernmost peninsula of Eurasia, Europe is generally 'divided' from Asia to its east by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting...

. The article was published in Connaissance des temps (Knowledge of the times).

Lepaute also created a group of catalogs of the stars which were useful for the future of astronomy. She calculated the Ephemeris of the Sun, the Moon and the Planets for the years 1774-1784.

Nicole Lepaute took care of her terminally ill husband from 1767 until his death in 1774, after which her own health was also severely damaged. She adopted her husband's nephew, Joseph Lepaute Dagelet, future member of the French Academy of Science, in 1768.
