A one-and-a-half-mile-wide asteroid is making an in depth — however secure — strategy to Earth on Wednesday, and novice astronomers will be capable to watch by way of a livestream from the consolation of their properties.
The rocky object, referred to as the 1998 OR2, handed by no nearer than about four million miles, in accordance with NASA.
It made its closest strategy to Earth simply earlier than 6 am ET. The Digital Telescope Challenge, operated by Italian astronomer Gianluca Masi, could have a livestream on its web site starting at 2:30 p.m. ET because it continues to fly previous Earth.
Whereas many astronomers think about 1998 OR2 to be making an in depth strategy to the planet, it’s nonetheless very far-off.
Thus far, in truth, that it can’t be seen with the bare eye or a small telescope, the European House Company tweeted. The asteroid is “simply on the restrict of what’s seen with medium-sized telescopes,” the company wrote.
In line with NASA, the dimensions of 1998 OR2, which is categorized as “probably hazardous,” makes it vivid sufficient to be seen with some novice astronomy gear.
Paul Chodas, the supervisor of NASA’s Middle for Close to Earth Object Research program, stated folks hoping to catch a glimpse of the asteroid can accomplish that utilizing moderate-sized telescopes and below darkish skies.
To trace it, he prompt utilizing the Sky & Telescope’s star chart. Chodas stated the asteroid will seem as a star “shifting very slowly by means of the fastened stars.”
NASA started monitoring the article in July 1998 after it was found by the group’s Close to-Earth Asteroid Monitoring program.
“Because of this, we perceive its orbital trajectory very exactly, and we are able to say with confidence that this asteroid poses no risk of impression for at the very least the subsequent 200 years,” NASA wrote in a press launch. “Its subsequent shut strategy to Earth will happen in 2079, when it is going to go by nearer — solely about 4 occasions the lunar distance.”
Giant asteroids making an in depth strategy are uncommon, most just lately in September 2017 when the 3-mile-wide Florence whizzed previous Earth.
