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).

(155140) 2005 UD (provisional designation 2005 UD) is an asteroid on an eccentric orbit, classified as a near-Earth object of the Apollo group.It was discovered on 22 October 2005, by the Catalina Sky Survey at the Catalina Station in Arizona, United States. 2005 UD is thought to be a possible fragment of 3200 Phaethon due to its similar orbit, [8] [9] although it is not dynamically associated ...
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.
This category includes near-Earth asteroids listed as potentially hazardous objects.. The asteroids are sorted numerically by 0-padding either their minor planet number to 6 digits, or, if absent, the year of discovery when using their provisional designation.
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.
Phaeton (alternatively Phaethon / ˈ f eɪ. ə θ ən / or Phaëton / ˈ f eɪ. ə t ən /; from Ancient Greek: Φαέθων, romanized: Phaéthōn, pronounced [pʰa.é.tʰɔːn]) is a hypothetical planet hypothesized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the ...
