The asteroid (3200) Phaethon is widely recognized as the parent of the Geminid meteoroid
stream. However, it has never shown evidence for ongoing mass loss or for any form of …

Small bodies are capable of delivering essential prerequisites for the development of life,
such as volatiles and organics, to the terrestrial planets. For example, empirical evidence …

In this review presented at the Royal Society meeting,'Cometary science after Rosetta', I
present an overview of studies of small solar system objects that exhibit properties of both …

We report the discovery of a comet-like tail on asteroid (3200) Phaethon when imaged at
optical wavelengths near perihelion. In both 2009 and 2012, the tail appears≳ 350''(2.5× 10 …

The practical distinctions between asteroids and comets, viewed as products of accretion on
either side of the snow line, are less clear-cut than previously understood. In this chapter, we …

We present a study of planet-crossing asteroid (3200) Phaethon at three successive
perihelia in 2009, 2010, and 2012, using the NASA STEREO spacecraft. Phaethon is clearly …

Comets and asteroids have traditionally been considered two distinct separate populations
of small bodies in the solar system, according to their different dynamical, observational, and …

Context. The study of asteroids that present sporadic cometary activity is of fundamental
importance to address several astronomical problems including the end states of comet …

Abstract The near-Earth asteroid (3200) Phaethon is the parent body of the Geminid meteor
stream. Phaethon is also an active asteroid with a very blue spectrum. We conducted …

Context. The recently discovered Apollo asteroid 2005 UD is the most likely candidate for
being a large member of the Phaethon-Geminid stream Complex (PGC). Aims. Detecting …
