Huge ‘Potentially Hazardous’ Asteroid Hurtling Towards Earth

 

A huge 1km-wide asteroid is hurtling towards Earth, prompting astronomers to label it “potentially hazardous”. But don’t pack for Mars just yet – the large space rock, ‘2014 JO25’, is anticipated to move our planet safely. in step with NASA, the encounter on April 19 is the closest the asteroid involves Earth in 400 years, and no projected future encounters are as close for a minimum of another 480 years. However, another fly-by is anticipated in 2091 and also the space rock also makes regular close approaches to Mercury 


An asteroid of this size won't have as close an encounter with Earth for quite 10 years. "The next known flyby by an object with a comparable or larger diameter will occur when 800-meter-diameter asteroid ‘1999 AN10’ approaches within one lunar distance in August 2027," NASA said.

The asteroid was discovered by the Mt. Lemmon Survey in May 2014. Astronomers describe it as a “bright object” and believe it'll be among the most effective targets for radar observations this year.

2014 JO25’ has been designated as a potentially hazardous asteroid (PHA) by the planetoid Center. PHA’s are asteroids larger than 100 meters that may come closer to Earth than 7,495,839km (about 4,658,000 miles), which is adequate to 19.5 ‘Lunar distances’.

Despite the 2014 JO25’s designation as a PHA, projections predict it'll travel by Earth at a secure distance of about 1.8 million km (4.57 lunar distances). Two other big asteroids, ‘2003 BD44’ and ‘1999 CU3’, which are both nearly 2km wide, will locomote our planet shortly, however, they won’t come as close as 2014.

Astrowatch report 1,781 PHAs were detected on Sunday, however – happily – none of them is on a projected collision course with Earth.
