| | Astronomers briefly thought Elon Muskâs car was an asteroid. Hereâs why that points to a broader problem
<a href=https://kra27c.cc>skraken зеÑкалП</a>
Seven years after SpaceX launched Elon Muskâs cherry red sports car into orbit around our sun, astronomers unwittingly began paying attention to its movements once again.
Observers spotted and correctly identified the vehicle as it started its extraterrestrial excursion in February 2018 â after it had blasted off into space during the Falcon Heavy rocketâs splashy maiden launch. But more recently, the car spawned a high-profile case of mistaken identity as space observers mistook it for an asteroid.
Several observations of the vehicle, gathered by sweeping surveys of the night sky, were inadvertently stashed away in a database meant for miscellaneous and unknown objects, according to the International Astronomical Unionâs Minor Planet Center.
An amateur astronomer noticed a string of data points in January that appeared to fit together, describing the orbit of a relatively small object that was swooping between the orbital paths of Earth and Mars.
The citizen scientist assumed the mystery object was an undocumented asteroid and promptly sent his findings to the MPC, which operates at the Harvard Smithsonian Center for Astrophysics in Cambridge, Massachusetts, as a clearinghouse that seeks to catalog all known asteroids, comets and other small celestial bodies. An astronomer there verified the finding.
And thus, the Minor Planet Center logged a new object, asteroid â2018 CN41.â
Within 24 hours, however, the center retracted the designation.
The person who originally flagged the object realized their own error, MPC astronomer Peter Veres told CNN, noticing that they had, in fact, found several uncorrelated observations of Muskâs car. And the centerâs systems hadnât caught the error. | | | | Rosaura (Hôte)
