Rapporté par l'IA

Un astéroïde d'une taille approximative à celle de la sculpture Cloud Gate de Chicago doit survoler la Terre le 18 mai. L'objet, baptisé 2026 JH2, passera quatre fois plus près de la planète que la Lune. Il mesure environ 20 mètres de diamètre et pourra être observé avec des télescopes ou via une retransmission en direct.

L'astéroïde 2026 JH2 se rapproche actuellement de la Terre. Selon les rapports disponibles, son approche la plus proche est prévue pour le 18 mai. La distance de ce survol sera nettement inférieure à l'orbite habituelle de la Lune autour de la planète.

NASA's Artemis II astronauts have surpassed the halfway point to the Moon following Wednesday's translunar injection burn, continuing smooth progress on the historic 10-day mission—the first crewed trip beyond low Earth orbit since Apollo 17. The crew is on track for a lunar far-side flyby tomorrow and observations on April 6.

Asteroid 2026JH2 to pass Earth at close distance next week

An asteroid designated 2026JH2 will fly past Earth at a distance of 90,917 kilometres on 18 May. The object measures between 16 and 36 metres across and carries enough mass to damage a city if it struck, though experts confirm no impact risk for at least a century.

Four astronauts aboard NASA's Orion spacecraft Integrity conducted a close flyby of the Moon's far side on April 6, marking humanity's first in-person look in over 50 years. The crew came within 4,000 miles of the surface, streaming low-resolution video due to communication constraints. High-resolution footage will follow after the mission.

NASA sets Artemis II moon flyby for April launch

NASA has rescheduled the Artemis II mission, the first crewed trip to the moon since 1972, for an April liftoff from Florida. The 10-day flight will carry four astronauts on a lunar flyby without landing, testing key systems for future missions. Commander Reid Wiseman leads the crew, which includes the first Canadian astronaut to venture to the moon.

Unusual planet pair challenges traditional formation models
