A Manhattan-sized comet will safely pass near Mars in late October 2025, offering a rare science opportunity.
A comet about the size of Manhattan is expected to pass near Mars in late October 2025, according to Harvard astrophysicist Avi Loeb.
The object, roughly 1.5 kilometers in diameter, will approach within about 1 million kilometers of Mars, posing no threat to the planet or Earth.
Loeb called the flyby a rare scientific opportunity to study a large comet’s composition and trajectory, with NASA and other agencies monitoring the event using orbiters and telescopes.
The comet’s origin is uncertain but likely from the outer solar system.
