The Hubble Space Telescope is known for its high-resolution images of distant objects that are far outside the Sun’s small family of planets. Those distant galaxies are not just a long way away; they are also very large. Hubble can produce images of our own neighborhood, as here, in which the objects are much smaller as well as much nearer. Neptune has a diameter that is much less than a millionth of the distance across the whole Solar System, which itself is tiny compared to the distance to the nearest star, and tiny again compared with a galaxy.
