At the time, the presence of a huge world so close to its star was not compatible with theories of planet formationand was considered an anomaly. These changes are caused by the planet's gravitational effects from just 7 million kilometres' distance from the star.

ECUVILLON A., ISRAELIAN G., PONT F., SANTOS N. & MAYOR M. Located at a distance of about 50 light years away, the planet 51 Pegasi b is a hot Jupiter, because it has a orbital period less than 10 days (4.23 days) and similar in characteristics with the largest planet in the Solar system, having a mass of about 0.47 mass of Jupiter.
