Mars has two satellites, unlike Venus who has no natural satellites. Mars’s two satellites are Phobias and Demos, which scientist believed are captured asteroids. Mars was named after the God of War. Interestingly, this is the complete opposite of love, the god that Venus was named after. Mars does not have as many volcanoes as Venus.
1. The relationship between Mercury’s rotational period and orbital period is a resonance. This results from the Sun’s tidal force on Mercury and its very elliptical orbit. The sun cannot lock Mercury into a 1:1 rotation due to Mercury’s high eccentricity. Mercury takes 59 Earth days to rotate and and 88 days to orbit so it spins three times for every two orbital periods.
Astronomers from WISE say that with the new infrared observations, Baptistina is not the responsible party leaving the Origin of the Asteroid a mystery to scientists. Immediate Impact on Earth The asteroid which collided with Earth 66 million years ago immediately created a deep hole, known as the peak ring, with an area of 100 kilometres wide and 30 kilometres deep, leaving the crater mainly under sea. Just after the impact deep granite bedrock, in liquid form, rebounded up to 10 kilometres tall before falling into a circular ridge. Next, the peak ring was enclosed in a layer of rocks, called a breccia, that contains bits of broken rock and impact melt. The Chicxulub asteroid originally landed near the town of Chicxulub which is where the asteroid got its name.
The cratering record is evidence that Venus resurfaced within the past half-billion years. In the most recent cratering, Venus destroyed older craters. Geological conditions covered much of the older craters, older sediments also evolved. Studies suggest that the resurfacing occurred in the past half-billion years. 11) Describe four ways Mars is similar to Earth today.
Our planet, Feuer Leava, is habitable because of its place in the solar system, its atmosphere, and its formation. First, Feuer Leava is the second closest planet to the star, Vega. Vega is the only star in this solar system. It is 2.26 times larger than the sun, 7 times brighter, and approximately 2 times hotter. Feuer Leava does not rotate, so one side is constantly facing the star.
The astronauts ' prints are a bit too clear and could’ve only been made in wet sand. ‘That 's nonsense’, said Bad Astronomy’s Plait. Moondust, or regolith, is "like a finely ground powder. When you look at it under a microscope, it almost looks like volcanic ash. So when you step on it, it can compress very easily into the shape of a
Many people could be given credit for finding Neptune but John Couch Adams and Urbain-Jean-Joseph Le Verrier got most all of the credit. It was the first planet to be discovered by telescope but the first planet to be found by people specifically searching for one. It was launched in August 1977 the spacecraft went to Jupiter in 1979 and Saturn in 1981. After it went there it was programmed to go to Uranus in 1979 and last Neptune in 1989. The data and 10,000 pictures it took increased the knowledge of Neptune majorly.
If I could travel to another planet for a vacation it would be venus. The trip would be very interesting and always exciting. Venus is the second planet from the sun. It is the closest planet to Earth, and it is also the most similar to Earth in size, mass, volume, and density. Venus is very hot and dry and is always veiled in layers of clouds.
The less dense areas were gapped and more spacious, while the dense parts of the sea of gas were being clumped together by gravity. These clumped areas would soon for stars and galaxies. All distant galaxies are slightly red in color, and the redness of the galaxies can reveal how the universe was born. 13.5 billion-years ago the universe was mostly made of hydrogen gas. Hydrogen is the most simplest of gases, but is a tremendous source of power.
The latest data from the Mars Curiosity Rover suggests that Mars had a continental crust similar to the one Earth has. Researchers analyzed data collected with the rover’s ChemCam instrument (short for Chemistry and Camera) and determined that the composition of the rocks on Mars was reminiscent of Earth’s crust. Mars More Like Earth Than Ever The new evidence from the Mars Curiosity Rover supports the notion that many scientists have held lately, that Mars was once much more like Earth than previously thought. Because of what researchers had previously known of the Martian surface, that it was covered in dark igneous rocks similar to the ones that make up the underwater crust of the Earth, Mars was thought of as being a basaltic planet.
