Caramba,
já é o segudo planeta descoberto com pequenos instrumentos, mas este se superou, foi usado um telescópio de minúsculos 10 cm de abertura ! Ai já é apelação !
Tb quero brincar.

Flagstaff, AZ—Fifteen years ago, the largest telescopes in the world had yet to locate a planet orbiting another star. Today telescopes no larger than those available in department stores are proving capable of spotting previously unknown worlds. A newfound planet detected by a small, 4-inch-diameter telescope demonstrates that we are at the cusp of a new age of planet discovery. Soon, new worlds may be located at an accelerating pace, bringing the detection of the first Earth-sized world one step closer.
"This discovery demonstrates that even humble telescopes can make huge contributions to planet searches," says Guillermo Torres of the Harvard-Smithsonian Center for Astrophysics (CfA), a co-author on the study.
This is the first extrasolar planet discovery made by a dedicated survey of many thousands of relatively bright stars in large regions of the sky. It was made using the Trans-Atlantic Exoplanet Survey (TrES), a network of small, relatively inexpensive telescopes designed to look specifically for planets orbiting bright stars. A team of scientists co-led by Edward Dunham of Lowell Observatory, Timothy Brown of NCAR, and David Charbonneau (CfA), developed the TrES network...

A diminuição do brilho da estrela é o indicativo da presença do planeta. Os pequenos telescópios foram utilizados para detectar esta variação de brilho:
