These two asteroids are also the two most massive in the sample.<\/figcaption><\/figure>\n<p dir=\"ltr\">By reconstructing the objects\u2019 shapes, the team realised that the observed asteroids are mainly divided into two families. Some are almost perfectly spherical, such as<a href=\"https:\/\/www.eso.org\/public\/news\/eso1918\/\"> Hygiea<\/a> and Ceres, while others have a more peculiar, \u201celongated\u201d shape, their undisputed queen being the<a href=\"https:\/\/www.eso.org\/public\/news\/eso2113\/\"> \u201cdog-bone\u201d asteroid Kleopatra<\/a>.<\/p>\n<p dir=\"ltr\">By combining the asteroids\u2019 shapes with information on their masses, the team found that the densities change significantly across the sample. The four least dense asteroids studied, including <a href=\"https:\/\/www.eso.org\/public\/images\/eso2114d\/\">Lamberta and Sylvia<\/a>, have densities of about 1.3 grams per cubic centimetre, approximately the density of coal. The highest, <a href=\"https:\/\/www.eso.org\/public\/images\/eso2114e\/\">Psyche and Kalliope<\/a>, have densities of 3.9 and 4.4 grammes per cubic centimetre, respectively, which is higher than the density of diamond (3.5 grammes per cubic centimetre).<\/p>\n<p dir=\"ltr\">This large difference in density suggests the asteroids\u2019 composition varies significantly, giving astronomers important clues about their origin.<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\"><em>\u201cOur observations provide strong support for substantial migration of these bodies since their formation. In short, such tremendous variety in their composition can only be understood if the bodies originated across distinct regions in the Solar System,\u201d<\/em><\/p>\n<p dir=\"ltr\">explains Josef Hanu\u0161 of the Charles University, Prague, Czech Republic, one of the authors of the study. In particular, the results support the theory that the least dense asteroids formed in the remote regions beyond the orbit of Neptune and migrated to their current location.<\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"1600\" height=\"900\" src=\"https:\/\/www.youtube.com\/embed\/uGSHpUPN6CI?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<p dir=\"ltr\">These findings were made possible thanks to the sensitivity of the Spectro-Polarimetric High-contrast Exoplanet REsearch (<a href=\"https:\/\/www.eso.org\/public\/teles-instr\/paranal-observatory\/vlt\/vlt-instr\/sphere\/\">SPHERE<\/a>) instrument mounted on ESO\u2019s<a href=\"https:\/\/www.eso.org\/public\/teles-instr\/paranal-observatory\/vlt\/\"> VLT<\/a> <a href=\"https:\/\/www.eso.org\/public\/news\/eso2114\/?lang#2\">[2]<\/a>.<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\"><em>\u201cWith the improved capabilities of SPHERE, along with the fact that little was known regarding the shape of the largest main belt asteroids, we were able to make substantial progress in this field,\u201d<\/em><\/p>\n<p dir=\"ltr\">says co-author Laurent Jorda, also of the Laboratoire d&#8217;Astrophysique de Marseille.<\/p>\n<figure id=\"attachment_24587\" aria-describedby=\"caption-attachment-24587\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.eso.org\/public\/images\/eso2114d\/\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"24587\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=24587\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2021\/10\/eso2114d1.jpg\" data-orig-size=\"700,360\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;ESO\/Vernazza et al.\/MISTRAL algo&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;These images have been captured with the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument on ESO\\u2019s Very Large Telescope as part of a programme that surveyed 42 of the largest asteroids in our Solar System.
