Jupiter From New Horizons
Since the pictures weren’t taken from Earth there seems little point placing them in Google Sky as if they were being viewed from Earth - in fact, because we’re much closer to the sun we never see a crescent Jupiter from Earth. So instead , I’ve removed Io and used the imaging date given in the NASA press release (February 28 2007, 01:40) to locate and scale it as seen from the point of view of the spacecraft, which at the time was 2.3 million km from Jupiter and 800 million km from Earth.
Here’s the file for viewing in GoogleSky:
Jupiter from New Horizons (2.7MB)
The file also includes overlays of Earth, the Sun and Pluto (New Horizons’ primary target) for size and distance comparison. Again these are positioned from the point of view of the space probe.
For the astro-referencing I used the online JPL Horizons interface (no relation to New Horizons) which very cleverly allows you to generate an ephemeris for one Solar System object observed from any other major body, including spacecraft!
