AN ASTRONOMER has spotted a mile-wide asteroid hurtling toward Earth.
Nasa has categorized the asteroid as a “potentially hazardous object” – but nothing that warrants desperate action to save Earth.
Any object that comes within 30million miles of Earth is classified as a “near-Earth object”.
The asteroid, 名前付き “7335 (1989 JA)”, has the menacing distinction of “potentially hazardous object” because it will come within five million miles of Earth.
7335 (1989 JA) will pass Earth from a distance of 2.5million miles of Earth on May 27th.
Nasa’s Jet Propulsion Lab records show this is the 12th time since 1916 this asteroid has dazzled past Earth – it’ll come around again in 2029.
An astronomer at The Virtual Telescope Project snapped a remarkable picture of 7335 (1989 JA) against the back drop of space.
“The potentially hazardous asteroid…is almost at its safe, minimum distance from us, being now very bright,” 書きました Gianluca Masi, an astronomer leading The Virtual Telescope Project.
The Virtual Telescope Project will host two ライブストリーム on the day the asteroid rips past Earth.
Much of the research on NEOs stems from Congressional actions in 1998 そして 2005 which compelled Nasa to log NEOs big and small.
ナサ reported there are about 40 NEOs per week and in 20 years of cataloguing, they’ve identified more than 18,000.
99.9% of NEO close approaches are asteroids, according to Nasa’s Center for Near Earth Object Studies (CNEOS).
に 1908, an asteroid exploded over Siberia with the force of 1,000 atomic bombs, decimating 500,000 acres in a historical occurrence remembered as the Tunguska Event.
The asteroid was just 30-メートル wide – small in comparison to 7335 (1989 JA).
Space agencies geolocating objects in space is an amazing demonstration in accuracy – modern science gives us the assurance that if a world-threatening asteroid were to approach, humans would react.
“An asteroid impact is the only natural disaster that can be prevented” a scientist with Nasa’s Planetary Defense Coordination Office 前記.
