Jupiter-family Comet D/1770 L1 (Lexell) was the first discovered Near-Earth Object (NEO), and passed the Earth on 1770 Jul 1 at a recorded distance of 0.015 au. The comet was subsequently lost due to unfavorable observing circumstances during its next apparition followed by a close encounter with Jupiter in 1779. Since then, the fate of D/Lexell has attracted interest from the scientific community, and now we revisit this long-standing question. We investigate the dynamical evolution of D… 


ExploreNEOs. VIII. Dormant Short-period Comets in the Near-Earth Asteroid Population
We perform a search for dormant comets, asteroidal objects of cometary origin, in the near-Earth asteroid (NEA) population based on dynamical and physical considerations. Our study is based on
Dormant comets among the near-Earth object population: a meteor-based survey
Dormant comets in the near-Earth object (NEO) population are thought to be involved in the terrestrial accretion of water and organic materials. Identification of dormant comets is difficult as they
The Population of Tiny Near-Earth Objects Observed by NEOWISE
Only a very small fraction of the asteroid population at size scales comparable to the object that exploded over Chelyabinsk, Russia has been discovered to date, and physical properties are poorly
Gone in a Blaze of Glory: the Demise of Comet C/2015 D1 (SOHO)
We present studies of C/2015 D1 (SOHO), the first sunskirting comet ever seen from ground stations over the past half century. The Solar and Heliospheric Observatory (SOHO) witnessed its peculiar
With the NEOWISE portion of the Wide-field Infrared Survey Explorer (WISE) project, we have carried out a highly uniform survey of the near-Earth object (NEO) population at thermal infrared
An Early Look of Comet C/2013?A1 (Siding Spring): Breathtaker or Nightmare?
The dynamically new comet, C/2013?A1 (Siding Spring), is to make a close approach to Mars on 2014 October 19 at 18:30 UT at a distance of 40 ? 1 Martian radii. Such an extremely rare event offers a
Intrinsic Distributions of Cometary Perihelia and Magnitudes
Distrihutions of perihelia q and of absolute magnitude Ho are formed for a group of 256 long-period c?mets. These are considered to be representative of a much larger group of comets, many of which
