This is what happened with 2020 CD3. It is now orbiting at a distance farther from Earth. Such an asteroid is called a Temporarily Captured Object (TCO).<\/li>\n<li>The orbit of such objects is unstable. They have to contend with the gravitational influence of our permanent Moon as well as that of the Sun.<\/li>\n<li>Catalina Sky Survey (CSS) previously discovered 2006 RH120, which orbited Earth for some time that year, before it escaped in 2007.<\/li>\n<\/ul>\n<p><span style=\"color: #0000ff;\"><strong>For more such notes, Articles, News &amp; Views Join our Telegram Channel.<\/strong><\/span><\/p>\n<p><span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" title=\"Telegram Link\" href=\"https:\/\/t.me\/triumphias\" target=\"_blank\"><strong>https:\/\/t.me\/triumphias<\/strong><\/a><\/span><\/p>\n<p><span style=\"color: #0000ff;\"><strong>Click the link below to see the details about the UPSC \u2013Civils courses offered by Triumph IAS.<\/strong> <\/span><span style=\"color: #ff0000;\"><strong><a style=\"color: #ff0000;\" title=\"Courses available\" href=\"https:\/\/triumphias.com\/pages-all-courses.php\">https:\/\/triumphias.com\/pages-all-courses.php<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Relevance: Prelims: Science and technology Why in news?
