Dans la nuit de ce mardi, la planète rouge sera directement à l'opposé du Soleil sur la voûte céleste. La Terre se trouvera donc entre Mars et le Soleil, offrant une configuration qui montrera Mars plus grande dans les télescopes.

Ce phénomène d'opposition fera en sorte que Mars deviendra momentanément plus brillante que Jupiter.

Le Planétarium de Montréal signale que les amateurs d'astronomie auront la chance de voir Mars passer à plus de 50 degrés au-dessus de l'horizon, une position bien plus enviable pour son observation que lors de la dernière opposition survenue en 2018.

Mars sera par la suite visible du crépuscule à l'aube toutes les nuits d'octobre.

Mardi dernier, le 6 octobre, la planète Mars était au plus près de la Terre, à une distance de 68 millions de kilomètres.
