Moving at 135,000 km/h relative to what? (honest question)

  I presume relative to the solar barycenter, and Wikipedia says that speed is its maximum speed (at perihelion of about 1.3 AU). For reference, Earth does a mean speed of about 107,000 km/h relative to the solar system's center of mass.

  I guess relative to the stars in the image, using parallax.

    No, relative to the stars it's going a LOT faster than that! Most likely it's relative to the sun.
