170 Maria is a bright-coloured Main belt asteroid. It is probably a mixture of silicate rocks and metallic iron-nickel.
It is the namesake of the Maria asteroid family.
It was discovered by J. Perrotin on January 10, 1877. Its orbit was computed by Antonio Abetti, and the asteroid was named after his sister, Maria.
An occultation of a star by Maria was observed from Manitoba, Canada, on June 10, 1997.
