what is the relationship between the distance from the sun and the orbital period quizlet?

Planets move in an elliptical orbit, with the Sun being one focus of the ellipse. A line between the sun and the planet sweeps equal areas in equal times. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

However, our planet's distance from the Sun has little effect on the onset of seasons. In fact, Earth is closest to the Sun, or at its Perihelion, around the Northern Hemisphere's winter solstice, while it is farthest away from the Sun, or at its Aphelion, around the north's summer solstice.

Kepler's third law of planetary motion says that the square of the planet's orbital period is proportional to the cube of its semimajor axis. For now, just read that as saying that a planet's 'year' is determined ONLY by its average distance from the Sun.

There is no connection between a planet's distance from the Sun and its rate of rotation (spin on its own axis or Planetary Rotation Period). While it is true that, generally speaking, the gas giants have higher rotation rates than the earth like planets closer to the Sun, any correlation is only coincidental.

It is about 886 million miles (~1.43 billion km) from the Sun and about 793 million miles (~1.3 billion km) from Earth. Saturn is about 9.5 times farther from the Sun than Earth is. Saturn is almost twice as far from the Sun as Jupiter, the 5th planet, is.

For objects in the Solar System, this is often referred to as the sidereal period, determined by a 360° revolution of one celestial body around another, e.g. the Earth orbiting the Sun. ... For example, Jupiter has a synodic period of 398.8 days from Earth; thus, Jupiter's opposition occurs once roughly every 13 months.

1 Answer. On an average, the Sun is about 390 times farther away from the Earth than the moon.

It is about 4.22 light-years from Earth and is the closest star other than the sun. Alpha Centauri A and B orbit a common center of gravity every 80 years. The average distance between them is about 23 astronomical units (AU) — a little more than the distance between the sun and Uranus.

The calendar year is typically 365 days. However, Earth's orbit around the sun takes slightly longer than this. Because of this difference, every fourth year of our calendar is called a leap year, and has 366 days. The differences arise because it actually takes the Earth around 365.25 days to make a full orbit.

What is the relationship between the average velocity of the satellite and its position in orbit? The satellite moves faster when it is closer to the primary. What is the relationship between the areas swept by the line connecting the earth and the satellite during equal time periods? They are both the same.

Saturn is 8.867 × 108 miles away from the Sun. Uranus is 1.787 × 109 miles away from the Sun.

It is a unit of length equal to the average distance from Earth to sun, approximately 149,600,000 kilometers (92,957,000 miles). Only Earth can be assigned AU 1. Planets farther away would have AU greater than 1; planets closer would have AU less than 1.

For the outer planets they have further to go and a slower speed so their orbital periods are much longer than that of the earth. e.g. saturn is 9.5x further from the sun than the earth is, but its orbital period is 29.5x that of the earth. Planets shine in visible light only by reflected sunlight.

Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

The speed of Earth's orbit around the Sun is determined by the radius of the orbit, so it isn't changing, and our year is remaining constant in length.

The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.

The gravitational force between the Sun and the Earth is about 3.54x1022 N. This force keeps the Earth orbiting around the Sun. The gravitational force from the other planets does slightly affect the Earth's orbit, but the gravitational pull from the other planets and the Moon is still very small.
