Apophis is about 1,100 feet (340 meters) in width. It’s expected to safely pass close to Earth – within 19,794 miles (31,860 kilometers) from our planet’s surface – on April 13, 2029. This will be the closest approach to Earth by an asteroid of this size that scientists have known about in advance.
In fact, collisions of asteroids with the early Earth may have been the key to delivering water to our planet (e.g., Daly & Schultz, 2018), enabling life as we know it. Now, billions of years later, the influx of small bodies in the inner Solar System is much lower.
19 kwi 2024 · Abstract. Among the nearly 30,000 known near-Earth asteroids (NEAs), only tens possess Earth co-orbital characteristics with semi-major axes ~1 au. In particular, 469219 Kamo‘oalewa (2016 HO3...
1 paź 2024 · Each month, NASA’s Planetary Defense Coordination Office releases a monthly update featuring the most recent figures on NASA’s planetary defense efforts, near-Earth object close approaches, and other timely facts about comets and asteroids that could pose an impact hazard with Earth.
29 sty 2024 · On January 20, 2024, astronomer Krisztián Sárneczky detected an asteroid on an imminent collision course with Earth. Just hours later, it struck our planet’s atmosphere 50 km west of Berlin, producing a stunning fireball. Named '2024 BX1', this is just the eighth asteroid that humankind has sp
31 lip 2018 · Near-Earth Objects (NEOs) are asteroids and comets in orbits that bring them into the inner solar system, within 121 million miles (195 million km) of the sun, and also within roughly 30 million...
30 kwi 2024 · Since the late 20th century, astronomers and space agencies have taken steps to monitor the threat of large asteroids passing near Earth. International initiatives were established to detect, track, and characterize these celestial bodies to safeguard our planet from possible collisions.
