Eight new possible planets detected

Updated 4:40 PM ET May 8, 2000

WASHINGTON (Reuters) - European astronomers Monday reported detecting
signs that
eight planets, some of them possibly larger than Jupiter, may be orbiting stars outside
our
own solar system.

These discoveries bring the number of potential extrasolar planets to more than 40.
The
hunt for these planet candidates has intensified in the last year, as space scientists
from
around the world scan the heavens for Sun-like stars and planets that might orbit
them.

The newest candidates were detected by astronomers working with the European
Southern Observatory's La Silla observatory in Chile. The scientists are based in
Geneva,
Switzerland.

None of the planet candidates have ever been seen by humans, but scientists believe
they
are there because of the gravitational pull they exert on the stars they orbit.

Two of the eight new candidates may not be planets at all, the European scientists
said in a
statement, but could instead be brown dwarfs, which have a bit less mass than stars
and
completely lack a star's interior nuclear power source.

Three of the new planet possibilities are about the size of Saturn or smaller, three are
one
to three times the size of Jupiter and two are 10 times the size of Jupiter or larger.

All of these are far larger than Earth.
