The comet has a minimum orbit intersection distance with Earth of 0.013 AU (1.9 million km; 1.2 million mi) and V. Guth noticed in 1939 that the orbit of comet approached the orbit of the Earth both in the ascending and the descending node, on 4 August and 31 January and suggested that the comet could produce meteors.
C/2021 T4 (Lemmon) is a long period comet discovered by the Mount Lemmon Observatory on 7 October 2021. [1] This passage through the planetary region of the Solar System will reduce the orbital period from millions of years to thousands of years. [2] It has been south of the celestial equator since October 2022.
The Genesis Rock, returned by the Apollo 15 lunar mission in 1971. The sample return capsule from NASA’s OSIRIS-REx mission shortly after touching down in the desert in Utah. A sample-return mission is a spacecraft mission to collect and return samples from an extraterrestrial location to Earth for analysis. Sample-return missions may bring ...
COmet Rendezvous, Sample Acquisition, Investigation, and Return (CORSAIR) is a concept mission to return comet nucleus samples to Earth for detailed analysis.The mission concept was submitted in May 2017 by a team from NASA's Goddard Space Flight Center in response to the New Frontiers program call for mission 4, but did not pass the initial down selection.
As of 2022 there are no mission proposals to C/2014 UN 271, nor are there any upcoming missions that can be retargeted to the comet. The European Space Agency 's upcoming Comet Interceptor mission, which will launch in 2029 and make a flyby of a long-period comet within Earth's orbit, will not be able to reach C/2014 UN 271 due to its large ...
[5] [6] It is the first comet discovered with the synthetic tracking technique, made possible with the Tycho Tracker commercial software developed by Daniel Parrott. [5] When it was discovered, it had a magnitude of 19. It has a 124 day observation arc. [1] It came to perihelion on 19 February 2021. The next perihelion will be in early 2154.
