Asteroid ‘Kematian’ Apophis Akan Mendekat ke Bumi, Catat Tanggalnya VOI.id
NASA has confirmed that there is no risk of the near-Earth asteroid 99942 Apophis impacting our planet for at least the next 100 years. While early observations following its discovery in 2004 suggested a potential collision in the coming decades, rigorous tracking by astronomers has since ruled out such a scenario.
Despite the lack of impact risk, the asteroid is set to make an extraordinarily close flyby of Earth on April 13, 2029. During this event, Apophis will pass approximately 20,000 miles (32,000 kilometers) from the Earth’s surface—a distance closer than many satellites currently in geosynchronous orbit, which typically sit at altitudes around 22,236 miles (36,000 kilometers).
This rare astronomical occurrence will provide a unique opportunity for scientific study and public observation. The asteroid is expected to be visible to the naked eye as it blazes across the night sky, with the best viewing opportunities occurring over Africa and Europe. Monitoring such near-Earth objects is a critical component of planetary defense, ensuring global safety through the early detection and tracking of potentially hazardous objects.
To further understand the asteroid’s composition and behavior, NASA has redirected the OSIRIS-APEX spacecraft to study Apophis during its April 2029 approach. Researchers intend to use the spacecraft’s thrusters to stir up surface dust and rocks, allowing scientists to examine the material just beneath the asteroid’s exterior. Earth-based telescopes will also be utilized for close observation.
First discovered on June 19, 2004, by astronomers Fabrizio Bernardi, David J. Tholen, and Roy A. Tucker at the Kitt Peak National Observatory, Apophis measures approximately 450 meters (1,480 feet) by 170 meters (560 feet). The asteroid’s name is derived from the Greek version of Apep, the Ancient Egyptian serpent known as the “Uncreator” and enemy of the sun-god Ra.
