(155140) 2005 UD has a similar orbit to (3200) Phaethon, an active asteroid in a highly eccentric orbit thought to be the source of the Geminid meteor shower. Evidence points to a genetic relationship between these two objects, but we have yet to ful

The classical approach to estimate an asteroid's mass is to analyze its gravitational interactions with another object such as a spacecraft, Mars, a companion asteroid, or a separate asteroid during an asteroid-asteroid close encounter. The latter ca

The mass of an asteroid is considered one of its fundamental properties. Knowledge of an asteroid's mass is, by itself, useful for spacecraft navigation particularly for space missions planned to the asteroid in question. The gravity of massive aster

We study observations of a fireball that occurred in Kylmälä, Finland with the aim of determining its Keplerian orbital elements. The fb_entry program is used to determine the fireball’s trajectory based on the observations. The orbit is then det
