It depends on what you mean by rotate. A planet in a locked orbit to its star doesn’t rotate with reference to its star; it rotates once (in essence its day) in the same period as its year (orbital period) from an external viewpoint.
To get a planet that doesn’t rotate in respect to the rest of the universe is far harder. It would have to rotate in the opposite direction to its star orbit with a day period exactly equal to its year.
Saturn and Jupiter show off: How to watch the planets rule August nights - CNET
Saturn, with its glorious rings, is a gem in the night sky. Jupiter, the jumbo gas giant, is another looker and some of its moons can be seen with binoculars. August is a prime viewing month for both planets.
The night of Sunday, Aug. 1, and morning of Monday, Aug. 2, marked Saturn's opposition -- when it was lined up with the sun and Earth was in the middle, like a celestial sandwich. Jupiter's opposition is coming up on Aug. 19.
What would happen if two gas planets like Jupiter collided? - BBC Science Focus Magazine
Although orbital dynamics make it highly unlikely that two gas giants would collide, there's a small chance that such an impact could happen during the formation of a planetary system. The result of a collision mainly depends on the speed and angle of impact.
Head-on collisions would generally lead to a complete merger of the gas giants without any loss of material, either in their solid cores or in their gaseous envelopes. However, a higher speed head-on collision would likely lead to the loss of most of the envelope gas as the two cores merge.
Astronomers Measure Rotation Speeds of Planets in HR 8799 System | Astronomy | Sci-News.com
Using the Keck Planet Imager and Characterizer (KPIC) on the Keck II telescope at the W.M. Keck Observatory, astronomers have obtained and analyzed the high-resolution spectra of the four giant planets orbiting HR 8799.

Mountain Skies Saturn At Opposition This Morning - The Transylvania Times
Of all the planets we can view through binoculars or a small telescope, the most fascinating to a first-time observer would be the four large Galilean moons of Jupiter and the rings of Saturn.
This is, of course, due to the earth's rotation, not any motion on Saturn's part. But we know Saturn does move as it orbits the sun; so, what effect doe that have? It takes the ringed planet almost thirty years to go around the sun.
Nearby star resembles ours in its youth -- ScienceDaily
Many people dream of meeting with a younger version of themselves to exchange advice, identify the origins of their defining traits, and share hopes for the future. At 4.65 billion years old, our Sun is a middle-aged star.
Without a time machine to transport scientists back billions of years, retracing our star's early activity may seem an impossible feat. Luckily, in the Milky Way galaxy -- the glimmering, spiraling segment of the universe where our solar system is located -- there are more than 100 billion stars.
Dragon Ball: 10 Planets That Were Destroyed (& How) | CBR
Akira Toriyama's Dragon Ball has grown into one of the most iconic anime series of all time, and it's incredible how its popularity in recent years seems to dwarf its massive success in the '90s.
Dragon Ball begins grounded on Earth, but it increasingly heads to the recesses of outer space in pursuit of treasures and obstacles on new planets . It's been exciting for Dragon Ball's characters to experience the wonders of the galaxy and even explore alternate universes.
Top-rated telescopes and binoculars for stargazing in 2021
According to the American Meteor Society (AMS), there are currently three active meteor showers. Two of the three — Southern delta Aquariids and Alpha Capricornids — peaked between July 28 and 29, but you can still see them through the end of August.
Whether you watch celestial events in your backyard , on a rooftop or at a park, bringing along a telescope or a pair of binoculars will only enhance the experience of watching stars, planets and meteor showers. Here are 12 top-rated products that will help you see into outer space.
Southwest Research Institute mission to Jupiter’s Trojan asteroids nears launch date
Boulder's Southwest Research Institute is leading a first-of-its-kind space mission to explore Jupiter's Trojan asteroids, a project seven years in the making that scientists hope will shed light on the origins of our planetary system.
The Lucy spacecraft will travel 4 billion miles over 12 years to study eight asteroids. The 46-foot, one-ton craft built by Lockheed Martin was transported from Buckley Space Force Base in Aurora to NASA's Kennedy Space Center on Friday, where it will undergo further testing before its Oct.
