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).

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 ...
Phaeton, a planet situated between the orbits of Mars and Jupiter whose destruction supposedly led to the formation of the asteroid belt. This hypothesis is now considered unlikely, since the asteroid belt has far too little mass to have resulted from the explosion of a large planet.
Most meteor showers originate from comets, but the Geminids come from 3200 Phaethon, an asteroid. The Geminids first appeared in the mid-1800s. At the time, there were 10 to 20 meteors an hour ...
While most meteor showers originate from comets, the Geminids actually come from an asteroid called 3200 Phaethon. NASA researchers say the asteroid acts like a "weird" comet .
Earlier this year, using data from NASA’s ongoing Parker Solar Probe mission, astronomers had found that the Geminid meteors — which are made up of debris from an asteroid named 3200 Phaethon ...
The disruption hypothesis suggests that a planet which was positioned between Mars and Jupiter was destroyed, creating the asteroid belt between these planets. First proposed by astronomer Heinrich Wilhelm Matthias Olbers, scientists in the 20th century dubbed this hypothetical planet "Phaeton".
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.
