Saturn’s Moons The planet of Saturn is an amazing planet as far as moons go. This planet is currently known to have fifty-two moons. Some of these moons are spherical in shape much like Earth’s moon and some look to be no more than a meteor that was captured by the huge planet. Now I’m not going to be able to discuss every moon that belongs to Saturn but I will talk about the six biggest which are: Titan, Rhea, Iapetus, Dione, Tethys, and Enceladus. All of Saturn’s moons were named after Greek Mythological figures.
Is there a lot of economic benefit from going to the moon? NASA has discovered a lot of water on the moon. In 2009 NASA crashed a rocket into the moon. NASA says they have detected 100 kg of water. This led many people to suggest that water should be extracted from the moon since we are running out of fresh water here on earth.
Gravitational forces from both the sun and moon continuously pull on the Earth. It is the moon's gravity that is the force behind the Earth's tides. Every particle on Earth is pulled on by the gravity of the moon. Because liquids move more easily, the pull of gravity is much more noticeable in liquids than in solids. The moon's pull is strongest on the part of the Earth directly facing the moon.
Mars is the fourth planet from the sun formed approximately 4.5 billion years ago. The planet Mars is known as the “Red Planet” for obvious reasons. That reason being that the planet glows red. The soil on Mars contains a composition that is very rich in iron. So when the tornado like dust storms take place the dust becomes a canopy.
This finding of the impact crater is very important because that implies the rocks at the rim of crater provide give scientists more information about the origin of the moon, the moon in the ancient time. Comparing the number of impact craters on the Earth to the Moon and other terrestrial worlds, we could say that it is very rare. There are many reasons that could explain why other planets will be more impact craters than the Earth, for example, Earth’s atmosphere, geological activity, and human activities could be responsible to the phenomenon of lost impact craters on the Earth. First, the Earth’s atmosphere, a lot of smaller meteorite or comet cannot get through Earth’s atmosphere. They burn up after entering the Earth’s atmosphere, thus a lot of them did not make
(Mars, 4) Second, it has a source of energy, and third, it has water. (Mars, 4) Mars is more than 100 million miles away from earth. (Mars, 1) Deciding where to send a rover is not an easy job, for Mars’ exploration scientists and engineers. (Politics of Landing, 1) They have looked for sites that will help us understand Mars’ ability to support life. (Politics of Landing, 1) One way scientist tried to find life on Mars was to send the Phoenix Mars Lander mission to Mars.
Three of the four inner planets (Venus, Earth, and Mars) have atmospheres substantial enough to generate weather. All of the inner planets have impact craters and tectonic surface features such as rift valleys and volcanoes. The first of the inner planets, and closest planet to the Sun, is Mercury. It is the smallest planet in the Solar System and has no natural satellites. Its only known geological features are impact craters and lobed ridges or rupes (steep slopes or cliffs), probably produced
Phases of the Moon Animated Phases of the Moon By observing the Moon over a period of several weeks, one will notice that the Moon rises and sets at different times each night, and that there is a regular progression through lunar phases. In a synodic month, the Moon progresses through one lunar cycle and will vary between being a completely dark new moon and a fully illuminated full moon . The lunar phases are caused because the orbit of the Moon around the Earth will vary the Moon’s position in relation to the Sun. Half of the Moon is always lit by the Sun, but the portion that we see will change depending on where the Moon is in its orbit. The synodic month “begins” at new moon.
Venus also has the slowest rotation out of all the planets rotating around the sun every 243 Earth days. 5 .Why do Mercury and Earth’s Moon lacks an atmosphere? Mercury and the moon are so small and light they do not have enough gravity to hold on to an atmosphere. Also they are closer to the Sun so the sun burns off their gasses a lot quicker than ours. 8.
The lunar phases vary cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon and Sun. One half of the lunar surface is always illuminated by the Sun (except during lunar eclipses), and hence is bright, but the portion of the illuminated hemisphere that is visible to an observer can vary from 100% (full moon) to 0% (new moon). The boundary between the illuminated and unilluminated hemispheres is called the terminator. Lunar phases are the result of looking at the illuminated half of the Moon from different viewing geometries; they are not caused by shadows of the Earth on the Moon that occur during a lunar eclipse. The Moon exhibits different phases as the relative geometry of the Sun, Earth and Moon changes, appearing as a full moon when the Sun and Moon are on opposite sides of the Earth, and as a new moon (also named dark moon, as it is
