Why are more massive planets circling stars easier to detect than low-mass planets?
What will be an ideal response?
As the planet circles the star, the star wobbles slightly, and that very small motion of the star is detectable by Doppler shifts in the star's spectrum. The Doppler shifts are more easily detected with larger-mass planets.
