The orbit of the asteroid Anteros and its position in the solar system
In 1992, it was considered as a potential target for the flight of the NEAR Shoemaker spacecraft, but due to the small size of Anteros, preference was given to the asteroid (433) Eros [4]
An asteroid approaches the Earth’s orbit and revolves around the Sun for 1.71 Julian years .
