The tiny dot in the center of the image is the newly discovered interstellar object 3I/ATLAS, previously known as A11pl3Z. The comet is only the third known interstellar object after 1I/ʻOumuamua and 2I/Borisov. 3I/ATLAS, which is around 24 kilometers (15 miles) in size, is currently 4.5 AU (Astronomical Unit, 1 AU is the Earth-Sun distance of 150 million kilometers or 93 million miles) away from the Sun. It is moving towards the inner solar system at a speed of 61 kilometers per second (38 miles per second).

The hyperbolic path of the interstellar comet is inclined to the ecliptic by 172 degrees. 3I/ATLAS will reach its perihelion in October 2025 at 1.38 AU from the Sun. That is closer than the planet Mars. After that, it will move away from the inner solar system.

This is the trajectory of the first two interstellar objects 1I/ʻOumuamua in red and 2I/Borisov in yellow. The comet 3I/ATLAS has a very high eccentricity of 6.

The first interstellar object 1I/ʻOumuamua was discovered in 2017. Its size is estimated to be between 100 and 1,000 meters. Its shape is unknown. It could be cigar-like or pancake-like or a spheroid.

This is a Hubble image of the rogue comet 2I/Borisov that was discovered in 2019. Its size is less than 500 meters. The objects in the background are stars.

Astronomers estimate that 10,000 interstellar objects are passing inside Neptune's orbit per day. Their size ranges from micrometers to kilometers.

The new Vera C. Rubin Observatory will provide more insights into these objects. The origin of the comet 3I/ATLAS could be in the thin galactic disk.
