Alpha Centauri, the nearest star to our solar system, is 4.3 lightyears away. Assume that Alpha Centauri has a planet with anadvanced civilization. Professor Dhg, at the planet's AstronomicalInstitute, wants to build a telescope with which he can find out ifthere are planets orbiting the sun.
What is the minimum diameter for an objective lens that will justbarely resolve Jupiter and the sun? The radius of Jupiter's orbitis 780 million {\rm km}. Assume lambda =600\;{\rm nm} .
