Since the star is visually bright and the planet is massive, it produces a very strong velocity signal of 469 ± 5 metres per second, which was quickly confirmed by Michel Mayor and Didier Queloz from data collected over 15 years.
由于其母星十分明亮，而其自身质量也较大，所以产生了十分明显的视向速度位移，速度高达每秒469 ± 5米/秒；而迈克尔·梅耶和迪迪尔·奎洛兹通过对15年间所收集数据的研究，证实了这一数据的准确性。
