The official confirmation that comet C/2019 Q4 is an interstellar comet has not yet been made, but if it is interstellar, it would be only the second such object detected. The first, ‘Oumuamua, was observed and confirmed in October 2017. ![]() This illustration depicts Comet C/2019 Q4’s trajectory. Deemed a possible interstellar object, it will approach no closer to Earth than about 190 million miles (300 million kilometers).

NASA study reveals new information about Interstellar Visitor OumuamuaNASA Jet Propulsion Laboratory
‘Oumuamua was too faint for Spitzer to detect when it looked more than two months after the object’s closest aproach to Earth in early September. However, the “non-detection” puts a new limit on how large the strange object can be. The results are reported in a new study published today in the Astronomical Journal and coauthored by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California. ![]() An artist’s concept of interstellar asteroid 1I/2017 U1 (‘Oumuamua) as it passed through the solar system after its discovery in October 2017. Observations of ‘Oumuamua indicate that it must be very elongated because of its dramatic variations in brightness as it tumbled through space. (European Southern Observatory / M.

NASA reports First Known Interstellar Object to enter our Solar System speeds up and changes directionsNASA’s Jet Propulsion Laboratory
“Our high-precision measurements of ‘Oumuamua’s position revealed that there was something affecting its motion other than the gravitational forces of the Sun and planets,” said Marco Micheli of ESA’s (European Space Agency) Space Situational Awareness Near-Earth Object Coordination Centre in Frascati, Italy, and lead author a paper describing the team’s findings. ![]() This artist’s illustration shows ‘Oumuamua racing toward the outskirts of our solar system, and is annotated with the locations of the planetary orbits. As the complex rotation of the object makes it difficult to determine the exact shape, there are many models of what it could look like.

NASA Study of Interstellar Object “Oumuamua” helps us understand Planet FormationWritten by Jeanette Kazmierczak
On October 19th, 2017, astronomers working with the NASA-funded Panoramic Survey Telescope and Rapid Response System (Pan-STARRS1) at the University of Hawaii spotted an object zipping through our solar system at a very high speed. Scientists at the Minor Planet Center, funded by NASA’s Near-Earth Object Observations Program, confirmed it was the first object of interstellar origin that we’ve seen. ![]() An illustration of ‘Oumuamua, the first object we’ve ever seen pass through our own solar system that has interstellar origins.
