When asteroid 2019 OK all of a sudden appeared towards Earth on July 25, 2019, Luisa Fernanda Zambrano-Marin and the group at Arecibo Observatory in Puerto Rico jumped into motion.


Having obtained an alert, radar scientists recognized the asteroid, which was coming from the Earth’s blind spot – the opposition to the Solar. Zambrano Marine and the group had half-hour to get as many radar readings as attainable. She was touring actually quick, and that is on a regular basis she was spending within the sights of Arecibo. UCF operates the Arecibo Observatory of the US Nationwide Science Basis underneath a cooperative settlement.

The asteroid grabbed the headlines as a result of it regarded prefer it got here out of nowhere and was touring quick.

Zambrano-Marin outcomes have been printed in Planetary Science Journal June 10, only a few weeks earlier than the worldwide observance of Asteroid Day, which is June 30, is selling international consciousness to assist educate the general public about these potential threats.

“It was a real challenge,” says Zambrano Marin, a planetary scientist on the College of California. “No one saw it until after it practically passed, so when we got the alert, we had very little time to act. However, we were able to get a lot of valuable information.”

It turned out that the asteroid was between 0.04 and 0.08 miles in diameter and was shifting quick. It rotated 3 to five minutes. Which means that it’s a part of solely 4.2% of recognized fast-rotating asteroids. This can be a rising group that researchers say wants extra consideration.

The info point out that the asteroid is probably going a kind C, which consists of clay and silicate rocks, or kind S, which consists of silicates and nickel iron. Sort C asteroids are among the many commonest and oldest asteroids in our photo voltaic system. Sort S is the second commonest.

Zambrano Marine is now checking the info collected by way of the Arecibo Planetary Radar database to proceed its analysis. Though the observatory’s telescope collapses in 2020, the Planetary Radar group can benefit from its present information financial institution spanning 4 a long time. Scientific operations proceed within the fields of house and atmospheric sciences, and employees are working to renovate the 12-meter antennas to proceed astronomy analysis.

“We can use new data from other observatories and compare it to the observations we’ve made here over the past 40 years,” says Zambrano-Marin. “Not only does the radar data help confirm information from optical observations, but it can help us determine physical and dynamic properties, which in turn can give us insight into appropriate diffraction techniques if they are needed to protect the planet.”

There are roughly 30,000 recognized asteroids in accordance with the Heart for Close to Earth Research, and whereas just a few pose a direct risk, there’s a chance that one of many giant asteroids may hit Earth and trigger catastrophic injury. Because of this NASA maintains a detailed watch and a system to detect and mark objects as quickly as they’re discovered. NASA and different house companies have launched missions to discover near-Earth asteroids to higher perceive what they encompass and the way they transfer in anticipation of the necessity to flip one route to Earth sooner or later.

The OSIRIS-REx mission, which incorporates UCSD Pegasus physics professor Humberto Campins, returns to Earth with a pattern of the asteroid Bennu, giving scientists just a few surprises. Bennu was first noticed at Arecibo in 1999. A brand new mission – NASA’s Double Asteroid Redirection Take a look at (DART) mission – goals to reveal the flexibility to redirect an asteroid utilizing the kinetic power of the projectile. The spacecraft was launched in November 2021 and is anticipated to succeed in its goal – the asteroid Demorphos – on September 26, 2022.

Zambrano-Marin and the remainder of the group at Arecibo are working to offer the scientific neighborhood with extra details about the numerous sorts of asteroids within the Photo voltaic System to assist make contingency plans.
