Mercury (planet) Mercury's surface is heavily cratered and similar in appearance to the Moon, indicating that it has been geologically inactive for billions of years. Mercury is gravitationally locked and rotates in a way that is unique in the Solar System.

- Earth's Moon is thought to contain substantial deposits of ice in deep craters in its polar regions, which never see direct sunlight. Mars, like Earth, has polar ice caps. On Uranus, meanwhile, the extreme tilt of the planet's axis leads to the poles alternately pointing almost directly at the Sun.

Giant-impact hypothesis The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact suggests that the Moon formed out of the debris left over from a collision between Earth and an astronomical body the size of Mars, approximately 4.5 billion years ago, in the Hadean eon; about 20 to 100 million years after the solar system coalesced.

The oldest and 'biggest ever' asteroid crater discovered in Greenland - suggesting huge impact more than three billion years ago Also the second largest impact structure on Earth, the 1.85 billion years old Sudbury crater in Canada, hosts world-class mineral deposits - in this case nickel-rich minerals that were melted and concentrated by the extreme heating caused by the impact.

Mars The Red Planet. Mars is a small rocky body once thought to be very Earthlike. Like the other terrestrial planets —Mercury, Venus, and Earth—its surface has been changed by volcanism, impacts from other bodies, movements of its crust, and atmospheric effects such as dust storms.

- During the first billion or so years of the Solar System a period of heavy bombardment, called the intense impact-cratering period, produced most of the impact craters seen on the Terrestrial planets. A by-product of the intense impact cratering was flooding with lava of immense impact basins to form the maria.

- Callisto [kah-LISS-toe] is the second largest moon of Jupiter, the third largest in the solar system, and is about the same size as Mercury. It orbits just beyond Jupiter's main radiation belt. Callisto is the most heavily cratered satellite in the solar system.Its crust is very ancient and dates back 4 billion years, just shortly after the solar system was formed.he largest craters have been erased by the flow of the icy crust over geologic time. Two enormous concentric ring, impact basins are found on Callisto. The largest impact basin is Valhalla. It has a bright central region that is 600 kilometers in diameter, and its rings extend to 3000 kilometers in diameter.

The earth's 100,000 Year Orbital Cycle However, my guess is, even when the earth's orbit has been at its most elliptical stages, its orbit was not very elliptical from the sun's point of view. It is more likely that the planets: Jupiter, Saturn, Uranus and Neptune would have the most destabilizing affect on the sun's core -- especially Jupiter.owever, my guess is, even when the earth's orbit has been at its most elliptical stages, its orbit was not very elliptical from the sun's point of view.

Planet of giant volcanoes? giant gas planet's four small inner moons. Earth is far from being the only planet where volcanism has played a salient role. HOWEVER.. Mars has many striking surface features, such as Olympus Mons (right), a giant volcano, three times the height of Everest, with a base 600 km in diameter. I think it's Mars.

10 Biggest Asteroid Craters on Earth According to scientists, the asteroid hit Earth 65 million years ago, thought to be a hint on what caused the mass extinction of the dinosaurs. (NASA) 3. Sudbury. The Sudbury Crater, in Ontario, Canada, is believed to been formed by a meteor blast over a billion years ago.

The Gas Giants Jupiter. Jupiter is by far the most massive of the planets. It is more than twice as massive as all the other planets put together; even so, it is only about 1/1000 the mass of the Sun. The most prominent features of Jupiter in the visible are the patterns in its clouds. We call the dark ones belts and the bright ones zones. An infrared picture of Jupiter (on the left below) shows variations in the temperature of its atmosphere: bright areas are warm and dark areas are cold.

Saturn Facts Eventually, deep inside, the hydrogen becomes metallic. At the core lies a hot interior. Saturn has the most extensive rings in the solar system: The Saturnian rings are made mostly of chunks of ice and small amounts of carbonaceous dust. The rings stretch out more than 120,700 km from the planet, but are are amazingly thin: only about 20 meters thick.

Hadley (crater) Note: this is an enlargement of the previous image of Hadley Crater. Hadley Crater is an impact crater in the Eridania quadrangle of Mars, located at 19.5°S latitude and 203.1°W longitude. It is 119.0 km in diameter and was named after George Hadley , and the name was approved in 1973.

How to spend from a 529 savings plan First of all, a 529 account can be used only to pay for expenses that are related to college or other post-secondary training institutions. While funds from a 529 account can be used to pay for expenses required for college, not all expenses qualify. Tuition and fees are considered required expenses and are allowed, but when it comes to room and board, the costs can’t exceed the greater of the following two amounts:

Asteroid Crash May Explain Mercury's Strange Spin Evidence of this collision might include Caloris Basin, Mercury's largest impact crater, which matches the predicted size, age and location of the impact, the researchers said. It is the perfect candidate, Correia said. Such an impact might also explain certain hollows seen on Mercury's surface.

- The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity. It has shield and composite volcanoes similar to those found on Earth. Relative to the Moon, Mars or Mercury, Venus has few small impact craters.fter the Moon, Venus was the second object in the Solar System to be explored by radar from the Earth. The first studies were carried out in 1961 at NASA 's Goldstone Observatory, part of the Deep Space Network.

- Mercury has many craters ridges,crarers and terrians.The other land on the planet is mostly smooth. Also one side of Mercury is very much more heavily cratored than the other.…   The surface of Mercury is a bit like that of the moon. There is no real atmosphere as the planet is too close to the sun and is not massive enough. It is pitted with billions …of craters, from meteor impacts, though as there is to atmosphere, there is no weather to errode the features away over time.

Which planet is most heavily cratered of the terrestrial planet? Confidence votes 2.9K. The most terrestrial planet in our Solar System is Mercury as evidenced by Mariner 10 satellite that flew by Mercury 3 times during 1974 and 1975. A new satellite, Messenger, was launched in 2004 and will be orbiting Mercury next year.

What Are They, and Where Are They? What Are They, and Where Are They? The terrestrial planets are nearly isolated worlds, with only Earth (1 moon) and Mars (2 moons) orbited by any moons at all. In contrast, many moons and rings orbit each of the jovian planets. All four jovian planets have rings, although only Saturn's rings are easily visible from Earth. Rings are composed of countless small pieces of rock and ice, each orbiting its planet like a tiny moon. The rings look flat because the particles all orbit in essentially the same plane.

- Venus is the most noticeable of the four, but Jupiter runs a close second. Look in the direction of sunrise as dawn begins to light the sky. Fainter Mars is also in the morning sky beneath Venus, and Mercury is the planet nearest the horizon at dawn. Meanwhile, Saturn is the lone evening planet this month.
