  Planet Observation Planet Observation: Astronomy: Saturn - Cassini-CASSINI AND HIS DISCOVERIES

CASSINI AND HIS DISCOVERIES

Giovanni Domenico Cassini (1625-1717) is famous for discovering the gap between the A and B rings of Saturn. He also proposed that the rings were made up of individual particles rather than being a solid body as many thought at the time.

  Planet Observation Planet Observation: Astronomy: Saturn - CAPTURING SATURN

CAPTURING SATURN

Saturn's low contrast and complex aspect make drawing it a major challenge. Many observers concentrate on potions-the Equatorial Zone or one side of the rings There is no time to dawdle— Saturn's quick rotation means that 15 minutes is long enough to work on a sketch.

SATURN

While Saturn and its rings have captivated observers for hundreds of years, the full wonder of this planet and its satellites is only just being realized.

  Planet Observation Planet Observation: Astronomy: Pluto - SEEING PLUTO

SEEING PLUTO

Pluto is a tough challenge for any planet watcher. At about 14th magnitude, it is a very faint object. You need a telescope of at least 8 inches (200 mm) to find it—but a 10 inch (250 mm) or larger scope makes the job a lot easier. With an apparent diameter ot less than 0.1 arcsecond, Pluto displays no visible disk and looks no different than a star.

  Planet Observation Planet Observation: Astronomy: Pluto - A MOON FOR PLUTO

A MOON FOR PLUTO

In 1978, James Christy discovered that Pluto has a moon. He named it Charon, after the mythological boat-man who ferried the souls of the dead across the River Styx to Hades. When astronomers determined Charon's orbit, they were startled to note that between 1985 and 1990, observers on Earth could see the Pluto-Charon system essentially edge-on, and watch the two bodies eclipse and occult one another every 3.2 days.

  Planet Observation Planet Observation: Astronomy: Pluto - Kuiper Belt-VISITOR FROM THE KUIPER BELT

VISITOR FROM THE KUIPER BELT

Pluto is an odd object. Its 248-year orbit is the most eccentric and inclined of all the planets, and, for part of it, Pluto travels closer to the Sun than Neptune does.

  Planet Observation Planet Observation: Astronomy: Pluto - Atmosphere-A LAYER OF GAS

A LAYER OF GAS

A second stroke ot luck occurred in June 1988, when Pluto passed in front of a 12th magnitude star. As they watched the star blink out, astronomers discovered that Pluto has a thin, cold ; atmosphere consisting mainly of nitrogen and methane.

PLUTO

There is an undeniable thrill in seeing this distant member of the Sun's family, and Solar System buffs cannot call their observations complete without it.

  Planet Observation Planet Observation: Astronomy: Planet Observation - ROCKS AND GAS

ROCKS AND GAS

You can sort planets into two categories—two ways. The first pair of categories refers to the planets' physical nature. Earth is a terrestrial planet, so too are Mars, Venus, and Mercury. Jupiter, on the other hand, is a gas giant, along with Saturn, Uranus, and Neptune.

  Planet Observation Planet Observation: Astronomy: Planet Observation - Observation-OBSERVING TIPS

OBSERVING TIPS

Planets are generally bright, so a dark observing site is less critical than it is for deep-sky objects. And since planets seldom stray more than a few degrees from the ecliptic, the site does not need to provide access to the entire sky.
