Stargazers Get Rare Look at Three Planets

CAPE CANAVERAL, Fla. (Dec. 9) -- Stargazers will get a rare triple
planetary treat this weekend with Jupiter, Mercury and Mars
appearing to nestle together in the predawn skies. About 45 minutes
before dawn on Sunday those three planets will be so close that the
average person's thumb can obscure all three from view.
They will be almost as close together on Saturday and Monday,
but Sunday they will be within one degree of each other in the sky.
Three planets haven't been that close since 1925, said Miami Space
Transit Planetarium director Jack Horkheimer.
And it won't happen again until 2053, he said.
"Jupiter will be very bright and it will look like it has two
bright lights next to it, and they won't twinkle because they're
planets," said Horkheimer, host of the television show "Star
Gazer. "This is the kind of an event that turns young children
into Carl Sagans."
The planets are actually hundreds of millions of miles apart,
but the way the planets orbit the sun make it appear they are
neighbors in the east-southeastern skies. They'll be visible in
most parts of the world - in the Western Hemisphere, as far south
as Buenos Aires and as far north as Juneau, Alaska, Horkheimer
said.
The experts differ on just how to look at the planets.
Horkheimer said naked-eye viewing is fine, but binoculars or a
telescope are even better.
But if you are going to use a telescope, be careful because the
planets are so close to where the sun will soon rise, if you linger
you might gaze at the sun through the telescope and damage your
eyesight, said Michelle Nichols, master educator at Chicago's Adler
Planetarium.
Ed Krupp, director of Los Angeles' Griffith Observatory,
cautioned it will be hard to see the event "with an unaided eye,
particularly in an area that is highly urbanized."
The way to find the planets, which will be low on the
east-southeast horizon, is to hold your arm straight out, with your
hand in a fist and the pinky at the bottom. Halfway up your fist is
how high the planets will appear above the horizon, Nichols said.
Jupiter will be white, Mercury pinkish and Mars
butterscotch-colored.
"It is a lovely demonstration of the celestial ballet that goes
on around us, day after day, year after year, millennium after
millennium," said Horkheimer. "When I look at something like
this, I realize that all the powers on Earth, all the emperors, all
the money, cannot change it one iota. We are observers, but the
wonderful part of that is that we are the only species on this
planet that can observe it and understand it."
In ancient times, people thought the close groupings of planets
had deep meaning, said Krupp. Now, he said, "it's absolutely
something fun to look for." |
