Planets are usually much brighter than stars. They are closer to earth so they begin to look more like a disk, rather than a tiny dot. Although some of the planets may be in their apparition period, they may be harder to see if they aren’t one of the brighter planets. Jupiter and Saturn will always be the easiest to see. Each planet reflects the light of the sun differently. Know what color you’re looking for in the night sky.  Mercury: this planet twinkles, flashing a bright yellow color. Venus: Venus is often mistaken for a UFO because it is large and silver. Mars: this planet is a reddish color. Jupiter: Jupiter glows white throughout the night. It is the second brightest point of light in the night sky.  Saturn: a smaller planet that is yellowish-white in color.

TL;DR in Chinese:
分清行星和恒星。 寻找明亮的行星。 知道你要找什么颜色行星。
