On the outward leg of its journey through the Solar System, ʻOumuamua passed beyond the orbit of Earth on 14 October with a closest approach distance of approximately 0.16175 AU (24,197,000 km; 15,036,000 mi) from Earth. [7] On 16 October it moved back north of the ecliptic plane and passed beyond the orbit of Mars on 1 November.
This artist's illustration shows 'Oumuamua racing toward the outskirts of our solar system. Figure 1 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.
However, subsequent investigations revealed further opportunities for missions to 'Oumuamua will be possible, using a Solar Oberth at 6 solar radii (4.2 × 10 ^ 6 km; 2.6 × 10 ^ 6 mi), [12] the soonest being in 2030/2033 – the choice of year depending on whether the trajectory exploits a 3 year leveraging maneuver or not.
The book describes the 2017 detection of ʻOumuamua, the first known interstellar object to pass through the Solar System. [8] [9] Loeb, an astronomer at Harvard University, speculates that the object might be an extraterrestrial artifact, [10] a suggestion considered unlikely by the scientific community collectively.
2I/Borisov, originally designated C/2019 Q4 (Borisov), [8] is the first observed rogue comet and the second observed interstellar interloper after ʻOumuamua. [9] [10] It was discovered by the Crimean amateur astronomer and telescope maker Gennadiy Borisov on 29 August 2019 UTC (30 August local time).
A giant solar sail recently unfurled by Nasa has been spotted “tumbling” through space.. Astronomers captured the 80-square-metre object, which was unfurled last week, appearing to fluctuate ...
Nasa has released a new map showing the path along the US – stretching from Texas to Maine – from where the total solar eclipse will be visible on 8 April 2024.. The rare cosmic event will be ...
The April 8 total solar eclipse path of totality touches 13 American states and hits some major U.S. cities along the way. An estimated 32 million people live within the U.S. section of the path ...
