This questions concerns our ability to detect a planet around anearby star via imaging. Assume you are using a space-basedtelescope with 1.4m diameter mirror. The image you obtain will be"diffraction-limited,since you won't be affected by the earth'ssurface.
Consider a star exactly like the sun(G2V), with the same luminosityand radius,10 parsecs from earth.
Determine whether you can detect a planet exactly like earth, at adistance of 1 AU from this star. That is,could you resolve the starand the planet as two separate bodies? Show why or why not
