3200 Phaethon (/ ˈ f eɪ. ə ˌ θ ɒ n /; previously sometimes spelled Phæton), provisionally designated 1983 TB, is an active [8] Apollo asteroid with an orbit that brings it closer to the Sun than any other named asteroid (though there are numerous unnamed asteroids with smaller perihelia, such as (137924) 2000 BD 19).

It will also observe dusts from comet/asteroid 3200 Phaethon using a dust analyzer and will map its surface using a multiband telescopic camera to understand the mechanisms of dust ejection. [2] The spacecraft will come as close as 500 km (310 mi) from 3200 Phaethon.
As recently as April of this year scientists have learned more about 3200 Phaethon. NASA reports research into the asteroid’s comet-like behavior found its tail was composed of sodium gas rather ...

"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said. A massive asteroid has a chance to hit Earth.
Phaethon's 1.4-year orbit around the Sun and its comet-like elliptical trajectory have led scientists to speculate if it is a "dead comet" or a distinct celestial entity known as a "rock comet." Despite its comet-like orbit, Phaethon lacks a cometary tail and exhibits spectra resembling a rocky asteroid.
Asteroid 2024 YR4 has a 1.3% chance of impacting Earth in 2032, NASA reports. Astronomers all over the world are watching the asteroid, trying to narrow down its future path.
