من المقرر أن يمر كويكب يبلغ حجمه تقريبًا حجم منحوتة "كلاود غيت" في شيكاغو بالقرب من الأرض في 18 مايو. وسيقترب هذا الجرم المعروف باسم 2026 JH2 من كوكبنا بمسافة أقرب بأربع مرات من المسافة بين الأرض والقمر. يبلغ قطر الكويكب حوالي 20 مترًا، ويمكن رصده عبر التلسكوبات أو من خلال بث مباشر.
يقترب الكويكب 2026 JH2 حاليًا من الأرض، ومن المتوقع أن يصل إلى أقرب نقطة له في 18 مايو، وفقًا للتقارير المتاحة. ستكون مسافة مروره أقرب بشكل ملحوظ من مدار القمر المعتاد حول الكوكب.

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.
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.

NASA's Psyche spacecraft is scheduled to pass within 2,800 miles of Mars on May 15 to gain a gravitational boost toward its target asteroid. The maneuver will increase the probe's speed while allowing tests of its scientific instruments.
A rare planetary alignment featuring six planets will be visible across the night sky from anywhere on Earth. The event excludes Mars, which is positioned on the opposite side of the sun. Observers can best view it on 28 February and 1 March.

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 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.

Astronomers have identified a rare planetary system 190 light-years from Earth featuring a hot Jupiter sharing its orbit with a mini-Neptune closer to the star. This configuration was once considered nearly impossible. New observations from the James Webb Space Telescope provide fresh insights into how the planets formed.
