Zambrano-Marin and the team had 30 minutes to get as many radar readings as they could. It was <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">travel<\/a>ing so fast, that&#8217;s all the time she&#8217;d have it in Arecibo&#8217;s sights. UCF manages the Arecibo Observatory for the U.S. National <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a> Foundation under a cooperative agreement.<\/p>\n<p>The asteroid made headline <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a> because it appeared to come out of nowhere and was traveling fast. <\/p>\n<p>Zambrano-Marin&#8217;s findings were published in the <i>Planetary Science Journal<\/i> June 10, just a few weeks before the world observes Asteroid Day, which is June 30 and promotes global awareness to help educate the public about these potential threats.<\/p>\n<p>&#8220;It was a real challenge,&#8221; says Zambrano-Marin, a UCF planetary scientist. &#8220;No one saw it until it was practically passing by, so when we got the alert, we had very little time to act. Even so, we were able to capture a lot of valuable information.&#8221;<\/p>\n<p>Turns out the asteroid was between .04 and .08 miles in diameter and was moving fast. It was rotating at 3 to 5 minutes. That means it is part of only 4.2 percent of the known fast rotating asteroids. This is a growing group that the researchers say need more attention. <\/p>\n<p>The data indicates that the asteroid is likely a C-type, which are made up of clay and silicate rocks, or S-type, which are made up of silicate and nickel-iron. C-type asteroids are among the most common and some of the oldest in our solar system. S-type are the second most common.<\/p>\n<p>Zambrano-Marin is now inspecting the data collected through Arecibo&#8217;s Planetary Radar database to continue her research. Although the observatory&#8217;s telescope collapsed in 2020, the Planetary Radar team can tap the existing data bank that spans four decades. Science operations continue in the areas of space and atmospheric sciences, and the staff is refurbishing 12-meter antennae to continue with astronomy research. <\/p>\n<p>&#8220;We can use new data from other observatories and compare it to the observations we have made here over the past 40 years,&#8221; Zambrano-Marin says. &#8220;The radar data not only helps confirm information from optical observations, but it can help us identify physical and dynamical characteristics, which in turn could give us insights into appropriate deflection techniques if they were needed to protect the planet.&#8221;<\/p>\n<p>There are almost 30,000 known asteroids according to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/cneos.jpl.nasa.gov\/stats\/totals.html\">Center for Near Earth Studies<\/a> and while few pose an im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>te threat, there is a chance one of significant size could hit the earth and cause catastrophic damage. That&#8217;s why NASA keeps a close watch and system to detect and characterize objects once they are found. NASA and other space agencies nations have been launching missions to explore Near-Earth Asteroids to better understand what they are made of and how they move in anticipation of having to divert one heading for earth in the future.<\/p>\n<p>The OSIRIS REx mission, which includes UCF Pegasus Professor of Physics Humberto Campins, is headed back to Earth with a sample of asteroid Bennu, which gave scientists a few surprises. Bennu was first observed at Arecibo in 1999.
