Rubin Observatory in Chile will discover millions of previously undetected objects in the solar system over the course of the coming decade.<\/p>\n<p>The discovery campaign, which is due to begin in earnest later this year, should expand the known small-body populations in the solar system by a factor of four to nine, said University of Washington astronomer Mario Juric, a member of the research team behind the open-source Sorcha simulation software.<\/p>\n<p>\u201cWith this data, we\u2019ll be able to update the textbooks of solar system formation and vastly improve our ability to spot \u2014 and potentially deflect \u2014 the asteroids that could threaten Earth,\u201d Juric said today in a news release.<\/p>\n<p>Several studies describing the software and the predictions have been accepted for publication by The Astronomical Journal. The project was led by researchers from Queen\u2019s University Belfast in collaboration with colleagues from UW, the Harvard &amp; Smithsonian Center for Astrophysics and the University of Illinois at Urbana-Champaign. The software\u2019s name is derived from the Gaelic word for \u201cbrightness.\u201d<\/p>\n<p>Sorcha starts with the Rubin Observatory\u2019s planned observing schedule, factors in how the telescope makes its observations, and matches up those capabilities with the best model for the current state of the solar system and its reservoirs of small bodies such as asteroids. <\/p>\n<p>\u201cAccurate simulation software like Sorcha is critical,\u201d said Queen\u2019s University astronomer Meg Schwamb, who led the research team. \u201cIt tells us what Rubin will discover and lets us know how to interpret it. Our knowledge of what objects fill Earth\u2019s solar system is about to expand exponentially and rapidly.\u201d<\/p>\n<p>The software suggests that, over the course of a 10-year campaign known as the Legacy Survey of Space and Time, the Rubin Observatory will map more than 5 million main-belt asteroids, 127,000 near-Earth objects, 109,000 Trojan asteroids that share Jupiter\u2019s orbit, 37,000 trans-Neptunian objects and about 2,000 orbit-crossing objects known as Centaurs.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<iframe loading=\"lazy\" title=\"The expected LSST Solar System small body inventory\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/fvpOfraHGGo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\"><\/iframe><br \/>\n<\/figure>\n<p>Jake Kurlander, a UW doctoral student&nbsp;who\u2019s the principal author of one of the studies, said Rubin\u2019s observations should double the number of known asteroids in the solar system in less than a year. \u201cRubin\u2019s unparalleled combination of breadth and depth make it a uniquely effective discovery machine,\u201d he said.<\/p>\n<p>The observatory\u2019s Simonyi Survey Telescope \u2014 which is named after the family of Seattle software pioneer Charles Simonyi \u2014 is designed to observe small bodies multiple times using different optical filters, revealing their surface colors. Past solar system surveys typically made observations using a single filter.<\/p>\n<p>&nbsp;\u201cWith the LSST catalog of solar system objects, our work shows that it will be like going from black-and-white television to brilliant color,\u201d said&nbsp;Joe Murtagh, a doctoral student at Queen\u2019s University.<\/p>\n<p>The Rubin Observatory team has already started making preliminary observations and will share some of those early images at a First Look event on June 23.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\">\n<p><em>Check out Sorcha.space for more information about the Sorcha simulation software.
