It actually can and is used to detect extrasolar planets, mostly through watching their transits, where they move in front of the star and block some of its light.

Are planetary systems around stars extremely rare?
No, although it is difficult to spot exoplanets, so only the larger ones are often found. Most systems with identified planets most likely have many other smaller planets that we cant detect. A planet the size of Earth or Mercury is nearly impossible to detect with current technology.
Why can't you see some planets at night?

Why cant you see extrasolar planets directly?
Mainly because of the vast distances to these objects, and their relatively small size. Although our best telescopes can see structures like galaxies in very fine detail, observing a planet-sized object even within our own galaxy is extremely difficult.
How can you survive on other planets?

They can. While human eyes can not "see" infrared light, humans can detect this light as "heat" on the surface of the skin.
