695 Bella is a minor planet orbiting the Sun.
Although this asteroid has dynamic properties that make it a candidate for the Maria family, the spectral properties of the object indicate it is most likely an interloper. Instead, it may have been spalled off from 6 Hebe or its parent body. 695 Bella and 6 Hebe orbit on opposite sides of the 3:1 Kirkwood gap, and the two have similar orbital elements.[2]
