It hit Earth&#8217;s atmosphere at an angle of 6.1 deg, relative to the ground, and began to glow at 162.7 km heigh south of Cap\u00e3o Comprido, RS. It headed north at 230700 km\/h, covering 243.6 km in 3.8 seconds, and disappeared 137.0 km heigh, east of Carlos Barbosa, RS.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_3827\" style=\"width: 650px\" class=\"wp-caption alignnone\"><img aria-describedby=\"caption-attachment-3827\" data-attachment-id=\"3827\" data-permalink=\"http:\/\/www.bramonmeteor.org\/bramon\/en\/earthgrazer-no-rs-pode-ter-origem-interestelar\/mapa3d001-3\/\" data-orig-file=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?fit=1224%2C675\" data-orig-size=\"1224,675\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Trajet\u00f3ria do Meteoro pela Atmosfera &#8211; Cr\u00e9ditos: BRAMON\" data-image-description=\"&lt;p&gt;Trajet\u00f3ria do Meteoro pela Atmosfera &#8211; Cr\u00e9ditos: BRAMON&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?fit=300%2C165\" data-large-file=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?fit=854%2C471\" loading=\"lazy\" class=\"wp-image-3827\" src=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?resize=640%2C353\" alt=\"Trajet\u00f3ria do Meteoro pela Atmosfera - Cr\u00e9ditos: BRAMON\" width=\"640\" height=\"353\" srcset=\"https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?resize=1024%2C565 1024w, https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?resize=300%2C165 300w, https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?resize=768%2C424 768w, https:\/\/i1.wp.com\/www.bramonmeteor.org\/bramon\/wp-content\/uploads\/2021\/06\/mapa3d001.jpg?w=1224 1224w\" sizes=\"(max-width: 640px) 100vw, 640px\" data-recalc-dims=\"1\" \/><p id=\"caption-attachment-3827\" class=\"wp-caption-text\">Meteor trajectory &#8211; Credits: BRAMON<\/p><\/div>\n<p>An earthgrazer is a meteor that grazes the Earth&#8217;s atmosphere and travels extensives distances in the upper layers of the atmosphere.
