Five planets are bright enough to find without any equipment: Mercury, Venus, Mars, Jupiter and Saturn. They shine steadily instead of twinkling like stars, and they all travel along the same line across the sky, the ecliptic, which is also the path of the Sun and the Moon.
Venus and Jupiter are the brightest. Mercury stays close to the Sun, so it can only be caught low in the west after sunset or low in the east before sunrise. Uranus and Neptune need binoculars or a telescope, and Neptune is best found with a star chart.
Every planet has its own page with the visible window, best time, direction and altitude for where you are, plus a step-by-step way to find it.
