Which terrestrial planet is tilted upside down? In February 2018, a closer look at the seven planets suggested that some could harbor far more water than the oceans of Earth, in the form of atmospheric water vapor for the planets closest to their star, liquid water for others, and ice for those farthest away. As of October 2017, there are 3,446 confirmed planets, 1,326 of which are classified as super-Earths. All planets listed are larger than 1.7 times the size of the largest planet in the Solar System, Jupiter. NASA announced the discovery of seven Earth-size worlds orbiting the TRAPPIST-1 star five years ago. Its magnetic field is only about 1 percent that of Earth's, and the planet has no known moons. Space and Terrestrial Robotic Exploration Laboratory, University of Arizona . The IAU defines a planet as a celestial body that is in orbit around the sun, has a nearly round shape, and has mostly cleared its orbital neighborhood of debris. In our solar system, planets like Jupiter, Saturn, Uranus, and Neptune fall in this category. The tenuous atmosphere surrounding Pluto is known as the Pluto-space environment. The name Earth is at least 1,000 years old. The color of the hexagon changed from a mostly blue hue to a more golden appearance during the Cassini mission. The hexagon does not move in longitude as other clouds are visible in the sky.
