Mercury and Venus' orbits (purple lines), seen initially from an observer on Earth, then from a position in space. Because Mercury and Venus orbit closer to the Sun than the Earth does, they can only be seen either just before sunrise or just after sunset. Mercury, the closest planet to the Sun, is often hidden in the Sun's glare. Venus, which is further out and can be seen when the sky is dark, is the brightest object in the sky apart from the Sun and Moon. | |
