2020cd3



With technology continuing to advance and allow researchers to collect enormous amounts of data. The new Center for Data-Driven Discovery (CD3), lead by professor of astronomy George Djorgovski, primary goal is to speed data-driven discoveries. 2020 CD3 is a tiny member of a class of asteroids whose orbits cross the Earth’s orbit. Occasionally, they come near or collide with the Earth, but in this case a collision would not have been a. Asteroid 2020 CD3 (Earth's minimoon) is currently in the constellation of Gemini. The current Right Ascension of Asteroid 2020 CD3 (Earth's minimoon) is 07h 39m 00s and the Declination is +23° 48’ 43” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom change ). 2020 CD 3 은 20152016년 즈음부터 약 45년간 지구의 두번째 위성으로 있었던 것으로 추정되며, 2020년 3월 7일 지구를 떠났을 것이라고 보고 있다. 다만, 일각에서는 준위성 으로 전환되거나 벗어날 때 쯤 달의 인력에 이끌려서 손자위성 이 될 가능성도 보고 있다. There is no chance of a collision in the short term. 2020 CD3 is in a rather chaotic orbit of the Earth that extends well beyond the moon and doesn't come very close to Earth Each orbit is different, but no orbit brings it closer than the moon.

NEODyS provides information and services for all Near-Earth Asteroids (NEAs). Each NEA has its own dynamically generated home page providing information and services, and a search facility putting the information in easy reach. Download rapoo driver.

Starting from 1 September 2011 NEODyS is sponsored by ESA, whichpays a portion of the operating costs, both for the background orbitand risk computations and for the database and web interface; the restof the cost is covered by the Department of Mathematics of theUniversity of Pisa, with the running research grants of the CelestialMechanics Group, and by IASF-INAF (Rome), with a PRIN-INAF grant.

The ESA participation is through a contract with SpaceDyS srl, acompany of Cascina (Pisa, Italy), which is a startup promoted by sameresearch group which has built and operated NEODyS in the past.

ESA isprogressively assuming larger responsibility for the operations ofNEODyS, under the programmatic envelope of the Space SituationalAwareness (SSA) initiative, NEO segment. The NEODyS service isexpected to be federated, together with others including theSpaceguard Central Node and the EARN Asteroid Database, in a newcomprehensive SSA-NEO information service.

The University and Research groups will in the near future continue to sharethe work and the responsibility, and are inany case committed to continue for a long period of time to contributewith research, innovation and certification functions.

This is the new version NEODyS-2, implementing the new error model based upon Veres, Farnocchia, Chesley, Chamberlin, Statistical analysis of astrometric errors for the most productive asteroid surveys, Icarus 296, 2017. The orbits have all been recomputed by using star catalog debiasing and an error model with assumed astrometric errors RMS deduced from the tests of the paper cited above. Risk files have bene recomputed for all PHAs, scanning for possible impacts in the coming century; as a result, many objects do not have anymore a risk file, because the orbit has improved.

The software used for this version of NEODyS is OrbFit version 5.0; the free distribution can be dowloaded through this link.

The NEODyS service is in some circumstances time critical (e.g.,during special observation campaigns for asteroids at risk of beinglost and/or with Virtual Impactors). At the moment we cannot provide aduplicate service to guarantee against network failures.


We are doing an effort to provide NEODyS with online help andcaptions. However, it is obviously not possible to explain all thetechnicalities involved in such a complex information system. The Tumbling Stone site had been created precisely to provide more user friendlyinformation, including an illustrated dictionary of technical terms,and comments on the most relevant events and discoveries about NearEarth Asteroids. Unfortunately this site is not currentlymaintained.


The same services for other asteroids, including all numbered and multiopposition orbit objects, can be accessed at AstDyS.


What's new?

  • The NEODyS information system has recently changed its web interface. This was necessary to allow upgrade and maintenance of the web interface, because the previous version used propietary software which we could not maintain and which used obsolete libraries. The new interface will gradually diverge, that is acquire new functionality. We would appreciate receiving comments on the new interface.

Other features

  • We are operating the impact monitoring service CLOMON2. Therisk pages have a new format and contain more information, includingthe Palermo Technical scale for each possible impact.
  • We are providing a link to the animated orbit diagramsavailable from JPL (e.g.,Apophis).
  • We are providing proper elements, computed by means ofsingular averaging, and encounter conditions; a figure shows thesecular evolution of the proper elements (e.g., Apophis).
  • We compute not only the Minimum Orbital Intersection Distance(MOID), but also all the stationary points of the distance functionbetween the orbit of the asteroid and the orbit of the Earth; a figure illustrates the geometry of the distance function; this is informativeespecially in the cases with multiple minima (e.g., Apophis).
  • We include the daily ephemeris for each object to thedatabase. This allows an observer to search for all NEODyS objectsthat are visible now, or are in a certain region of sky, in particulartaking into account the galactic disk. See the Search section to give it a try.
  • Radar observations now incorporated into our orbitalsolutions. For those objects with radar observations, this results insubstantially improved orbits, with far less uncertainty.
  • We are now using simpler and constant URL's. This means that you can put a link to your favorite asteroid (e.g., Apophis) or to your favorite observatory (e.g., Highland Road Park Observatory) on your own web pages. You can also usebookmarks now, the URL for an object does not change.

What's next?

  • We are working on the problem of assigning formal uncertainties,based upon the covariance matrix formalism, to all the quantitiespresented in the NEODyS home page of an asteroid. E.g., the periheliondistance, the MOID, the period, etc., should have a stateduncertainty.

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2020 CD3 (Earth's minimoon), according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.

The rise and set times are defined as the time at which the upper limb of Asteroid 2020 CD3 (Earth's minimoon) touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
