    How would you classify this? And what is the green line?

    Hi ninjamattyb and welcome to the Zoo

    The central object is a star from our galaxy.

    The green line is a satellite trail.
    The satellite reflects the sunlight and because of its speed it gets caught in just one filter.
    Satellite trails can also be blue or red.
