About the Object

  • Distance
    DistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
    The semi-major axis of Neptune's orbit about the sun is 30.06 astronomical units (roughly 2.8 billion miles or 4.5 billion kilometers).
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Neptune has a diameter of roughly 30,800 miles (49,600 kilometers) at the equator.

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image is a composite of separate exposures acquired by the WFC3/UVIS instrument. In the full globe and top detail image, several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F467M Green: F547M Red: F763M

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
