What Speed Do Planets Orbit The Sun? Our orbital speed around the sun is about 67,000 mph (107,000 km/h), according to Cornell. Do all the planets rotate around the sun at the same speed? In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the
Which Type Of Star Has The Largest Habitable Zone? Stars that are larger, hotter and more massive than the Sun (A-dwarfs) have their habitable zone much farther out from the star. What is the most habitable type of star? Habitable zones potentially capable of hosting life-bearing planets are wider for hotter stars. Smaller, dimmer red
Which Planet Is Most Like The Sun? It is not known if Kepler-452b is a rocky planet but based on its small radius, Kepler-452b is likely to be rocky. It is not clear if Kepler-452b offers habitable environments. It orbits a G2V-type star, like the Sun, which is 20% more luminous, with nearly the same
Which Gas Giant Has The Shortest Period Of Revolution? Mercury has the shortest period of revolution (about 88 days), and Pluto has the longest (about 248 years). Which planet has the shortest time of revolution? Mercury is an extreme planet in several respects. Because of its nearness to the Sun—its average orbital distance is 58
Why Is Jupiter Mostly Hydrogen? Structure. The composition of Jupiter is similar to that of the Sun—mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system—an ocean made of hydrogen instead of water. Why does planet
Why Is Jupiters Spot Red? The source of the red coloration is unknown; suggestions range from compounds of sulfur and phosphorus to organic material, any of which could be produced by lightning discharges or by high-altitude photochemical reactions. The Great Red Spot extends well above Jupiter’s main cloud layers. What causes Jupiter’s Red Spot? Jupiter’s
What Are Common Characteristics Of Planets? The characteristics of a planet are that it (a) is in orbit around the sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium [nearly round] shape, and (c) has cleared the neighborhood around its orbit. What do all
Why Is Venus The Hottest Planet Though It Is Not Closest To The Sun? Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth. As a result, temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is

Which Planet Is The Youngest? NASA scientists just announced the discovery of the youngest planet every found in the universe. The planet is named K2-33b, and closely orbits a new star — which makes the planet very hot. Is Mercury the youngest planet? Is it the oldest planet, or the youngest? Actually, you might be
