If NASA and other scientists can confirm that comets originated outside the solar system, it would be the second such object to be detected. The first is the Oumuamua. observed and confirmed in October 2017. So far, Comet C ≤ 2019 Q4 has advanced to the sun.

The comet will not be near the earth. Scientists say it will orbit farther than Mars and will not exceed 190 million miles from Earth. After the initial detection of comets, the NASA reconnaissance system at the Jet Propulsion Laboratory automatically marked the object as a potential interstellar object.

At present, the Comet is 260 million miles from the sun and will reach the nearest place to the sun on December 8, 2019. At this time, it is about 190 million miles from the sun. At present, the current speed of comets is as high as 93000 miles per hour. The team said the high speed indicated that objects originated outside the solar system and suggested that comets might return to interstellar space.

The comet's trajectory will see it passing through the ecliptic at an angle of 40 degrees. Comet C/2019 Q4 is considered a comet because its observations are blurred, indicating a central ice body. Comet C/2019 Q4 brightness will peak in mid-December.
