Giant asteroid flying by Earth next week looks like it’s wearing a face mask - 7NEWS.com.au
An observatory has spotted a strange discovery on an asteroid moving at 31,000 kilometres per hour.
An asteroid estimated to be 1.9 km wide will fly by Earth next week, but its not expected to collide with our planet. And if an asteroid could be aware of such things, it appears to be wearing a face mask in deference to the pandemic, according to new images from Arecibo Observatory in Puerto Rico. The asteroid is called 52768 (1998 OR2), and it was first spotted in 1998. On April 29, it will pass within 6.3 million kilometres of Earth, moving at 31319 kilometres per hour.

If it did impact Earth, the asteroid is large enough to cause global effects, according to NASA, back when the asteroid was first discovered. The small-scale topographic features such as hills and ridges on one end of asteroid 1998 OR2 are fascinating scientifically, said Anne Virkki, head of planetary radar at Arecibo Observatory, in a statement. But since we are all thinking about COVID-19, these features make it look like 1998 OR2 remembered to wear a mask.

The center tracks Near-Earth Objects, or NEOs, that could collide with Earth. Arecibo Observatory is a National Science Foundation facility managed by the University of Central Florida. A team of experts has been monitoring this near-Earth asteroid, among others. The observatory is supported by NASAs Near-Earth Object Observations Program and has been analysing asteroids since the mid-90s. During the pandemic, scientists at Arecibo are continuing to make their observations on behalf of planetary defense. In line with social distancing, they have limited the number of scientists and radar operators at the facility, and theyre wearing masks during observations.

The experts at Arecibo can monitor the asteroids and use observations to determine their path in the future to see if they pose a risk to Earth. The radar measurements allow us to know more precisely where the asteroid will be in the future, including its future close approaches to Earth, said Flaviane Venditti, a research scientist at the observatory. In 2079, asteroid 1998 OR2 will pass Earth about 3.5 times closer than it will this year, so it is important to know its orbit precisely.

That honor belongs to the asteroid 3122 Florence (1981 ET3), which flew by and luckily missed colliding with Earth on September 1, 2017. It will make another pass again on September 2, 2057.
