Um asteroide de tamanho aproximado à escultura Cloud Gate de Chicago passará pela Terra no dia 18 de maio. O objeto, conhecido como 2026 JH2, chegará quatro vezes mais perto do planeta do que a Lua. Ele mede cerca de 20 metros de diâmetro e pode ser observado com telescópios ou por meio de uma transmissão ao vivo.

O asteroide 2026 JH2 está se aproximando da Terra. De acordo com os relatórios disponíveis, espera-se que ele faça sua maior aproximação em 18 de maio. A distância de sobrevoo será notavelmente mais próxima do que a órbita habitual da Lua ao redor do planeta.

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.
