A gigantic asteroid, the size of a 25-storey building is fastly approaching the earth and it has already reached very close to the earth. The asteroid is 250 feet (76 metres) in length and is considered an Apollo-class near-Earth object (NEO).

( NewsNation) — Venus could be hiding asteroids that would be deadly if they hit Earth, some experts say. A new study published in the journal Astronomy and Astrophysics has shown that Venus has at least 20 co-orbital asteroids that could potentially approach the Earth.

A newly discovered house-size asteroid is set to make a close, yet harmless approach to Earth today (May 21), passing within one-third of the Earth-moon distance.

After leaving Earth, Tianwen-2 will reach Kamo‘oalewa by July 2026. This tiny, elongated asteroid likely spans no more than 130 to 330 ft (40 to 100 meters). It circles the Sun at a mean distance of 0.9 to 1.1 astronomical units (AU: the average Earth-Sun distance) with a sidereal period of 365.7 days, similar orbital parameters to Earth itself.

Astronomers are using data from the recently decommissioned star-mapping satellite to help determine masses and more accurate orbits of celestial bodies closer to home.

SpaceX's Starship faced a setback as its recent launch spun out of control, impacting its Mars mission ambitions. Meanwhile, Japan's ISC plans a U.S. launch to tackle rocket shortages, and China's Tianwen-2 mission marks its first attempt to retrieve asteroid samples,

If pollen allergies are getting to you, you are not alone. Every year, plants release billions of pollen grains into the air, specks of male reproductive material that many of us notice only when we get watery eyes and runny noses.

Data from NASA’s Dawn mission and simulations from Purdue University claim that up to 90% of Ceres’ outer shell may be made of dirty ice.
