2 unusual facts about Jérome Lalande


Atlas Coelestis

In 1795 it was published in an updated version, produced by Mechain and Lalande, with new constellations and many more nebulae.

Jasus lalandii

It is not known whom the specific epithet lalandii commemorates, although it may be the French astronomer Jérôme Lalande.


Acta Eruditorum

Since its inception many eminent scientists published there – apart from Leibniz, e.g., Jakob Bernoulli, Humphry Ditton, Leonhard Euler, Ehrenfried Walther von Tschirnhaus, Pierre-Simon Laplace and Jérôme Lalande but also humanists and philosophers as Veit Ludwig von Seckendorff, Stephan Bergler, Christian Thomasius and Christian Wolff.

Alexis Clairaut

He obtained an ingenious approximate solution of the problem of the three bodies; in 1750 he gained the prize of the St Petersburg Academy for his essay Théorie de la lune; the team made up of Clairaut, Jérome Lalande and Nicole Reine Lepaute successfully computed the date of the 1759 return of Halley's comet.

Crab Nebula

The exact time of the comet's return required the consideration of perturbations to its orbit caused by planets in the Solar System such as Jupiter, which Clairaut and his two colleagues Jérôme Lalande and Nicole-Reine Lepaute carried out more precisely than Halley, finding that the comet should appear in the constellation of Taurus.

Lalande 21185

The celestial coordinates of Lalande 21185 were first published in 1801 by French astronomer Jérôme Lalande of the Paris Observatory in the star catalog, Histoire Céleste Française.
