相比以前所使用的一些根据恒星重力引起的震动来探测行星的方法，凌日探测法可以发现体积小很多的行星。
Transit detection can pick up much smaller planets than previous methods based on gravity-induced wobbles in the stellar parent.
使用的物探方法有重力、地面和航空磁法、地面和航空电磁、IP／电阻率法、钻孔物探测井及地震反射。
Methods used have been gravity, ground and airborne magnetics, ground and airborne electromagnetics, IP/resistivity, downhole geophysical logging, and reflection seismic.
