Data from the Galileo spacecraft indicates that an iron core may form Io's center, thus giving Io its own magnetic field. Its magnetic field lines are twisted by Uranus' sideways rotation into a long corkscrew shape. More recently, this planet has been visited by passing spacecraft, orbiters and probes. Phobos, the innermost moon, is heavily cratered, with deep grooves on its surface. Scientists have long wanted to study comets in some detail, tantalized by the few 1986 images of comet Halley's nucleus. Results from New Horizons, besides forcing the revision of textbooks, left planetary scientists struggling to explain this cold, distant world and its system of moons. As the nebula collapsed because of its overwhelming gravity, it spun faster and flattened into a disk. With a radius of 43,440.7 miles (69,911 kilometers), Jupiter is 11 times wider than Earth. Neptune has six known rings. The men independently accounted for the irregularities in the motion of Uranus by correctly predicting the orbital elements of a trans-Uranian planet. Craters with rays (both light, as on Earth's moon, and dark, as sometimes seen on Mars) indicating freshness are found on Charon. With a surface age of about 4 billion years, Callisto has the oldest landscape in the solar system. Callisto was discovered on 7 January 1610 by Galileo Galilei. And as one of just two bodies between Earth and the sun, Venus periodically passes across the face of the sun — a phenomenon called a transit. Like our planet, Europa is thought to have an iron core, a rocky mantle and an ocean of salty water beneath its ice crust. That extra quarter of a day presents a challenge to our calendar system, which counts one year as 365 days. Jupiter's four largest moons — Io, Europa, Ganymede and Callisto — were first observed by the astronomer Galileo Galilei in 1610 using an early version of the telescope. Hungrier observers compared its craters to cheese and dreamed of an entire sphere made of delicious dairy products. The finding generated considerable excitement among scientists, as it provided evidence that the moon is geologically active in the present day. The ice giant Neptune was the first planet located through mathematical predictions rather than through regular observations of the sky. With a diameter of over 2,985 miles (4,800 km), Callisto is the third largest moon in our solar system and is almost the size of Mercury. The temperature drops below 3.5 million degrees Fahrenheit (2 million degrees Celsius) in the convective zone, where large bubbles of hot plasma (a soup of ionized atoms) move upwards.
DrNicoleFarmerMD — 2022-02-18 11:46:48 UTC Venus has no rings. That means 30 Earth-sized planets could fit in between Earth and the moon. This unique tilt causes the most extreme seasons in the solar system. Comets actually have two tails - a dust tail and an ion (gas) tail. Earth's lithosphere, which includes the crust (both continental and oceanic) and the upper mantle, is divided into huge plates that are constantly moving. A deep canyon is named for Diana, Roman goddess of the hunt. Energy from the core is carried outward by radiation, which bounces around the radiative zone, taking about 170,000 years to get from the core to the top of the convective zone.
