当天文学家用这种方法从地球上观测到一颗恒星在另一颗恒星前“走过”时，距地球较近的这颗恒星的重力就如同一个镜头，将较远的那颗恒星的光弯曲并放大。
In this method, when one star passes in front of another, as seen from Earth, the nearer star's gravity ACTS like a lens, bending and magnifying the more distant star's light.
HD 10180的小行星离得更近，转得更快，它的轨道距其恒星仅有不到200英里的距离，公转一周只需要28小时。
The small HD 10180 planet is even closer and faster, less than two million miles from the star and completing an orbit in about 28 hours.
