Paper we describe our method and its application to Pan-STARRS1 data. The concept is much cleaner thanĬonventional astrometry but is not easy to perform for large catalogs. Solving such a system provides absoluteĪstrometry for all the stars simultaneously. Distance Kilometers 407,169,960 Distance AU 2. Light takes 22 minutes and 38.1728 seconds to travel from Comet C/2022 A2 (PANSTARRS) and arrive to us. Radio positions, referenced to the ICRF2. The distance of Comet C/2022 A2 (PANSTARRS) from Earth is currently 407,169,960 kilometers, equivalent to 2.721763 Astronomical Units. Of Quasi-Stellar Objects (QSOs, or distant AGN) with very accurate (<1 mas) The GAS, based onĪ single, least squares adjustment to approximately 750k grid stars using overģ000 extragalactic objects as reference objects, avoids this catalog-to-catalog The current orbit shows it coming to perihelion in 2023 I will speculate wildly about possible prospects for this comet in tomorrow’s Sky Notes during the meeting at Burlington House. This is an image of it taken from Chelmsford a few minutes ago. Thus PS1 astrometry inherits the errors of the 2MASS catalog. Newly discovered C/2017 K2 (PANSTARRS) is currently around 16AU from the Sun and mag 19 or so. Current PS1 astrometry isīased on differential astrometric measurements using 2MASS reference stars, Pan-STARRS1 (the Panoramic Survey Telescope and Rapid Response System 1) is an optical and near infrared survey that covers the entire sky north of declination 30°, including the galactic plane.
