For the first time in 10 years, the planets have aligned –and they're preparing to put on a rare celestial show.

Mercury, Venus, Saturn, Mars and Jupiter, the five bright planets, are currently visible from Earth. Arching through the pre-dawn sky, high in the north and low in the east, the planets will be visible through Feb. 20. But there is a very specific time to see them at their brightest.

Venus, Mars, Jupiter and Saturn have all lit up the nighttime sky since the beginning of the year. Mercury, however, was the missing piece of the puzzle. It first began as a faint object low in the sky, but it's continuing its shift into sight and will park itself right below a glowing Venus.

“Mercuryfrom Feb. 4 through Feb. 7,” Jim Todd, director of space science education at Oregon Museum of Science and Industry in Portland, told The Columbian. That means that stretch of time is the best opportunity to see it clearly above the horizon with all the other planets.

According to International Business Times,Friday, Feb. 5 is your , as Earth's orientation "facing away from the center of the galaxy perfectly" will make the planets shine more brightly for backyard stargazers.

The trick to finding the planets? Follow the moon just before dawn. On Feb. 5, the waning crescent moon will appear closest to Venus. Venus and Mercury will be diagonally below the moon, while the rest of the planets follow the arch upwards. EarthSky has more specific this week and beyond.

Their initial appearance in late January marked the first time in more than 10 years all the planets could be seen with the naked eye, but it won't be the last time this year.

Dr. Tanya Hill, the senior curator at the Melbourne Planetarium, said there will be another chance to catch the five-planet lineup again this year in August, but after that, it will not be visible again until October 2018.
