How is Pluto's relationship with its moon Charon unlike the relationships between other planets and their moons?
They orbit about their mutual center of gravity, which is in between the two because they have similar mass. Other planets have the center of gravity inside them.
How many times does the earth cross the galactic equinox in 1 cycle of the galaxy?
The galactic alignment occurs once every 26,000 years but Earth crosses the Milky Way's galactic plane (also called the galactic equator) twice a year, every year.
What planet can orbit the sun four times in the amount of time it takes earth to orbit the sun once?
Mercury. Its the closest planet to the sun and only takes 88 days to orbit once around the sun.
When was the hubbe speca telescope HST first launchand into orbit?
It has only been launched into orbit once. That was in 1990.
The moon revolves around the earth once every 27.3 days and is 390.000 km from the center of the earth how long would it take a satellite launched to a distance of 6.700 km from the center of the eart?
For stable orbit @ 6 700 000 metres Velocity = sq. root ( G * mass earth / orbit radius ) = 7713.576 metres / sec Time for (sidereal) orbit = (2 * pi * radius) / velocity = 5457.56 seconds.
Does the sun orbit anything or does anything orbit it?
Yes - the sun slowly orbits the galactic center of our galaxy, The Milky Way. Also, everything in our solar system orbits the sun. That's what a "year" is - the amount of time it takes Earth to orbit the Sun once, about 365 days.
What day of the year is the earth closest to the center of the galaxy?
Every year the earth orbits the sun in the same plane as the galactic disk so it is closer to the galactic center by the diameter of the earth's orbit late June- July than it is in January when the sun is between the earth and the galactic center. That is also the time the earth is 5 million miles further from the sun (perhaps because it is the gravity from the galaxy that is distorting the orbit). One can not argue that the gravity of the galaxy is not keeping the solar system and all the othe stars in orbit around it! I would like to calculate what that gravitational force must be to balance the solar systems centripetal force acting to fling it outward. The Earth is closest to the center of the galaxy late June. We are perhaps not coincidentally both 5 million miles further away from the sun at that time, and at the same time we are on the side of the orbit that faces the galactic center. is it perhaps the gravity of the galaxy that is pulling on our earths orbit as well, making it slightly elliptic? The size of our orbit is less than one billionth the distance to the center of the galaxy, so comparatively we really aren't much closer. My astrophysicists friends say that we are too far from the center of the galaxy for it's gravity to have any significant influence upon us, although it is evident that the gravitational forces are strong enough to keep us and all the other stars in orbit around it. We have no idea of what still unknown other forces and energies might be emitted as the super black hole at the galaxies center as it slowly consumes the surrounding galaxy sucking the surrounding stars down the super massive black hole as the rest of the galaxy slowly turn about in the same way water turns as it's going down the drain pipe. The earths not quite circular orbit around the sun is in the same plane as galactic orbit. If any gravity or other influence from this super massive black hole and the combined mass of the rest of the galaxy arrives as far as we are, this field might vary when the sun and the galactic center are together overhead in January compared to when the sun and the galactic center are on opposite sides of us in late June early July. By coincidence, that the sun opposes the galactic center at around the same time the as the summer solstice, when the Northern Hemisphere is tipped toward the sun during the end of June. Therefore the Southern Hemisphere would be tilted toward the collect the center. Summer solstice This puts the galactic center square overhead and the sun behind us once a year for a few days around the June 23 solstace, at midnight, 0000hours, anywhere near the tropic of Capricorn (23.5 deg South) This latitude includes South Africa, Australia and Argentina. If there were to be any attempt to look for any galactic gravitational or 'radiation' variation, from a terrestrial viewpoint, this would be the best time and the best locations for observation.
How long does its takes to orbit the sun?
The Sun orbits around the galactic center of the Milky Way Galaxy and takes about 230 million Earth years to complete one Galactic Year. The Sun orbits the Milky Way Galaxy once about every two hundred twenty five million (225,000,000) years.
How long does it take the earth to complete its orbit around moon?
The Earth and the Moon mutually orbit their common center of mass once every 27.32 days. Their common center of mass is inside theEarth.
How is Pluto's relationship with its moon Charon unlike the relationships between other planets and their moons?
They orbit about their mutual center of gravity, which is in between the two because they have similar mass. Other planets have the center of gravity inside them.
How fast does the moon orbit around the earth?
-- Once in 27.32 days. -- About 2,280 miles per hour, relative to the center of the Earth.
What is the year length of the sun?
A Year is defined as the time it take a planet to orbit its star once. As the Sun is the star round which our solar system's planets orbit, the Sun itself can not have a year as it can not orbit itself. Therefore there is no year length for the Sun.However, the Sun, does revolve around the centre of the Milky Way Galaxy once ever ~235 million years - also called the Cosmic Year or Galactic year.that is 235 million years
How fast does the sun orbit the center of the galaxy?
About once every 200-225 million years. The fancy shmancy term for this is "Cosmic Year".
How do you measure a year in time on the sun if it has nothing to orbit around?
Normally when we talk about a "year", we refer to the "Solar Year" [See Link] which is the period that the Earth takes to revolve around the Sun once. However, there is another kind of year and that is a Galactic year [See Link] which is the time it takes the Sun (and all the planets) to revolve once around the galactic centre of the Milky Way Galaxy (Our Galaxy), so really, the Sun does have something to revolve around. The Galactic year takes around 225,000,000 Earth years
How long does it take the sun to travel around the Milky Way once?
It takes our sun roughly two hundred twenty million (220,000,000) years to orbit the galaxy. As the sun swings around, it passes back and forth through the plane of the galaxy, sort of like a sine wave.
How many times does the earth cross the galactic equinox in 1 cycle of the galaxy?
The galactic alignment occurs once every 26,000 years but Earth crosses the Milky Way's galactic plane (also called the galactic equator) twice a year, every year.
What is meant by revolving in an orbit?
Completing an elliptical orbit. The earth, for examples, revolves in its orbit around the sun once per year. The moon revolves in its orbit around the earth almost once per moonth.
