Planetary Science

The Sun has 109 times the diameter of the Earth, and therefore over a million times the volume. Its mass is about 330,000 times the mass of Earth.

All stars will burn out eventually. Polaris is about 430 LY away from us, and is a multiple star; there are several stars huddled together to form what we observe as one star. One component is a supergiant, and there is one main sequence star, and one dwarf. There are a couple of other small companion stars in the group. So the death of Polaris is likely to be a rather long and drawn out affair. It won't be fading from the sky any time soon.

Mars 2 was the first of many landers to reach the surface of Mars. Mars 2 was a Soviet probe launched on a Proton K rocket. The orbiter was a success, but the lander crashed on a Saturday, November 27, 1971.

The Soviet Mars 6 transmitted data during its descent, but was not heard from since before landing. It too may have crashed.

Viking 1 landed on Mars five years after the first Soviet attempt, on Tuesday, July 20th, 1976.

The ancient Greek philosopher Pythagoras is often credited with being one of the first to suggest that the Earth is a sphere, around the 6th century BC. His ideas were later developed and supported by other ancient Greek scholars like Aristotle and Eratosthenes.

Venus has an atmosphere that is so thick and dense that it is always cloudy. The clouds are composed of sulfuric acid droplets that completely obscure the planet's surface from view.

The Sumerians believed in astrology. They thought that events in daily life were affected by the positions of celestial bodies. We are glad they recorded those positions. We can calculate the exact dates of various events in their culture.

This question is impossible to answer as people are being born all over the world every day, all day.

Earth orbits around the sun faster than any of the outer planets. The appearance of retrograde motion occurs when earth moves past the other planet.

For comparison, from a car in the fast lane on the freeway, look at a slower car in the next lane and watch how it appears in relation to the scenery beyond it. The slower car will appear to move backwards in relation to barns and distant mountains. This effect can be quite startling when a faster train passes a slower train.

The odd behavior of the planets in the sky inspired thousands of years of mathematical and scientific study in hundreds of different cultures. Attempting to predict and explain planetary movement was the holy grail of worldwide science in nearly every part of the globe.

The sun rays are never overhead at any point beyond the tropical zone.the word TROPIC means turning point.when the sun has reached its northernmost and southernmost most limits on June 21st (tropic of cancer) and 22 December (tropic of Capricorn) respectively,it appears to turn southward and northward

There will be a total eclipse of the Moon on December 21, 2010.

The next total solar eclipse in Nova Scotia will be on April 8, 2024.

It takes an average of about 7 months to travel from Earth to Mars using current spacecraft technology, depending on the specific trajectory chosen and the positions of the two planets in their orbits.

Jupiter has a small moon called Cyllene, about 2 km accross.

Saturn has one called Calypso.

Uranus a small moon called Cordelia and another called Cupid.

Perhaps the most well known moon begining with `C` is Charon, a moon of the dwarf planet Pluto.

probaly because the planets didnt have names and everything was happening on earth

Pluto reflects sunlight rather than emitting its light due to its distance from the Sun. As an icy dwarf planet, Pluto's surface is highly reflective, with a low albedo that causes it to appear bright in our solar system.

For a planet to become a star, it must have enough mass to sustain nuclear fusion in its core. This typically requires a mass of at least 0.08 times the mass of our Sun, known as the hydrogen-burning limit. Below this threshold, the object would be considered a planet rather than a star.

Venus is 0.723AU from the sun. To convert this into fractions:

0.723 = 723/1000

If you round off the value from 0.723AU to 0.72AU, then the fraction would be:

720/1000 = 9/125

There is no special term except that the object is a member of the solar system. Millions of objects, (heavenly bodies) orbit the sun at varying distances going way out beyond the orbit of Neptune. Just a very very few (8, currently) are classed as planets.

food or edible things near by

Nuts because they contain high protein to keep your energy up and fats which is wat you would need if you were stranded

yep that yould be the best, but i would also say fruit from trees. I.E. cocanuts, and such... i think the most important thing is to stay hydrated.

This is a question that arose from another question I asked earlier today, but why is Neptune more dense than Uranus despite being close to the same size, but further from the sun? As I understand it, heavier elements should have been concentrated closer to the sun during the formation of the planets. The only theory I have heard is that Neptune somehow formed closer to the sun than Uranus, and drifted to a further orbit, but I received no explanation as to how that would happen.

Another theory I heard is that it formed from a larger amount of less dense material, and that mass compressed it, but as I understand it, larger volumes of less dense materials make for larger, thus less dense planets. For example, Jupiter despite it's huge mass is still less dense than any of the inner four planets.

hop this is what you needed... :)

Earth is the only planet in our solar system known to have significant bodies of liquid water on its surface. Some of Jupiter's moons, like Europa, Ganymede, and Callisto, are believed to have subsurface oceans of liquid water.

The Moon has less gravity than Earth, about 1/6th of Earth's gravity. This means that your weight on the Moon would be much less, making it easier to jump higher and move around. To stand on the Moon, you would need to wear a spacesuit to protect yourself from the harsh environment.

Rotate refers to turning something around a fixed point or axis, while revolve means moving in a circular or orbital path around a central point. Rotation typically involves a spinning or circular motion, whereas revolution involves an object traveling in a circular path around another object.

Saturn is the least dense planet because it is primarily made up of hydrogen and helium, which are the two lightest elements. These elements have low densities compared to the rocky materials that make up the inner planets like Earth. Additionally, Saturn's large size and low mass contribute to its overall low density.

Yes there are craters, and yes some of them are very deep. All craters, however, do in fact have a bottom. A bottomless crater would actually be best described as a "hole," and there are no holes through the Moon.

The center of mass is closer to the more massive object. It is the point at which the two objects orbit each other as if they were one system. The location of the center of mass is influenced by the masses and distances of the objects.
