NEARBY JUPITER: Lately have you noticed a very bright star rising in
eastern sky after sunset? That's Jupiter, the biggest planet in the solar
system. This weekend on Feb. 2nd, Earth and Jupiter will be closer
together than at any other time this year (Jupiter is "at opposition").
Even a small telescope will reveal the giant planet's cloudy belts and its
four largest moons. But you don't need a telescope to enjoy the close
approach. Jupiter is by far the brightest "star" in the evening sky--about
three times brighter than Sirius--and a lovely sight to the unaided eye.
If you miss Jupiter on Feb. 2nd, don't worry. This is just the beginning
of "Jupiter season"--a months-long stretch when the planet is easy to find
after sunset and visible well into the night.
