Full-Disk NeptuneNASA Information

Date: 08.20.1989

This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera.

The images were taken at a range of 4.4 million miles from the planet,

4 days and 20 hours before closest approach.

The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager's cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen.

Pluto•Double planet with Charon

•Solid

•-212 C

• Distant Worlds: Pluto and its moons are so distant and small even the Hubble Space Telescope can't resolve them clearly.

NASA Hot Topic Pluto and its companions are unlike the terrestrial and gas giant planets. Scientists believe Pluto and its companions in the Kuiper Belt are the planetary embryos from which the larger planets developed. The mission, of the New Horizons spacecraft, is a unique chance to study the early stages of planetary evolution and get a closer look at the region of space where many comets originate.NASA Official: Hashima Hasan

New Horizons

New Horizons would cross the entire span of the solar system -- in record time

Conduct flyby studies of Pluto and its moon, Charon, in 2015.

The seven science instruments on the piano-sized probe would shed light on the bodies' surface properties, geology, interior makeup and atmospheres.

Kuiper Belt

The "third zone" of the solar system known as the Kuiper Belt

Populated by smaller, icy objects different than the rocky inner planets or the outer gas giants.

Origin

An abbreviated version of a traditional Jewish religious blessing. The phrase, accompanied by a hand gesture, came to a wider

public in the Star Trek TV series. It was used there by the character Mr. Spock (actor Leonard Nimoy, himself Jewish) as the greeting of

the Vulcan people. http://www.phrases.org.uk/meanings/234750.html
