What does Kepler’s 2nd law say about planets orbiting the Sun?
Kepler's Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits. Basically, that planets do not move with constant speed along their orbits.
What does Kepler’s 2nd law say about the speed of the planets in regards to their distance from the Sun?
Kepler's Second Law Describes the Way an Object's Speed Varies along Its Orbit. A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves.
What does Kepler’s 2nd law state?
Kepler's Second Law says says that a line running from the sun to the planet sweeps out equal areas of the ellipse in equal times. This means that the planet speeds up as it approaches the sun and slows down as it departs from it.
Why is Kepler’s 2nd Law true?
Since the rate of change of angular momentum is zero, that angular momentum must be constant, which then says that the rate of change of swept-out area for the orbit of the celestial body must be constant. This then leads to Kepler's Second Law, that celestial objects in orbit sweep out equal areas in equal time.
Why planets move faster at near region of Sun and slower when they are far away?
When a planet is closer to the Sun the Sun's gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun's gravitational pull is weaker, so the planet moves slower in its orbit.
At what point if any during a planet’s elliptical orbit does the planet travel with the largest speed?
Kepler's 2nd Law of Planetary Motion dictates that a planet's fastest speed is at Perihelion and its slowest at Aphelion. (Kepler's 2nd Law of Planetary Motion: A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.)
Why do planets move faster at the near region of the Sun and slower when they are far away Class 11?
When a planet is closer to the Sun the Sun's gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun's gravitational pull is weaker, so the planet moves slower in its orbit.
Do planets that are farther from the Sun travel faster or do they travel slower?
Therefore the planet moves faster when it is nearer the Sun and slower when it is farther from the Sun. A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest). Law 3.
Does Jupiter orbit the Sun?
12 yearsJupiter / Orbital period
Does the planet obey Kepler’s second law?
Note that the time between each position shown is exactly one month. 1) Does this planet obey Kepler's second law? How do you know? – Yes, the planet obeys the Kepler's Second Law. It is because it moves at equal time of one month at the same distance.
How do you use Kepler’s second law?
Kepler's second law states that a planet moves in its ellipse so that the line between it and the Sun placed at a focus sweeps out equal areas in equal times.
Do planets closer to the Sun travel faster or slower than planets farther from the Sun?
Therefore the planet moves faster when it is nearer the Sun and slower when it is farther from the Sun. A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).
Why does the speed of a planet decrease as it moves away from the Sun?
Why does the speed of a planet decrease as it moves away from the sun? the direction of the sun's pull relative to the planet's motion changes. Which statement about the development of Newton's theory of universal gravitation is correct?
Which planet moves slowest around the Sun?
Venus Venus is the slowest – it rotates once every 243 days —- by far the slowest rotation period of any of the major planets. Sun is the nearest star. Planet with the slowest rotation: Venus.
Which planet travels around the Sun at the lowest speed?
What is the Slowest Planet. Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe.
Why do farther planets move slower?
A planet moves slower when it is farther from the Sun because its angular momentum does not change. For a circular orbit, the angular momentum is equal to the mass of the planet (m) times the distance of the planet from the Sun (d) times the velocity of the planet (v).
Why is a planet’s orbit slower the farther it is from the Sun?
A planet moves slower when it is farther from the Sun because its angular momentum does not change. For a circular orbit, the angular momentum is equal to the mass of the planet (m) times the distance of the planet from the Sun (d) times the velocity of the planet (v).
How does Jupiter travel around the Sun?
However, Jupiter does not technically orbit the sun — because it's so dauntingly massive. When a small object orbits a big object in space, the less massive one doesn't travel in a perfect circle around the larger one. Rather, both objects orbit a combined center of gravity.
What is the time taken by the Jupiter to revolve around the Sun?
Orbit and Rotation One day on Jupiter takes only about 10 hours (the time it takes for Jupiter to rotate or spin around once), and Jupiter makes a complete orbit around the Sun (a year in Jovian time) in about 12 Earth years (4,333 Earth days).
Where will an object move at the greatest speed as it orbits the Sun?
The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun).
Why planets move faster at nearer region of sun and slower when they are far away?
When a planet is closer to the Sun the Sun's gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun's gravitational pull is weaker, so the planet moves slower in its orbit.
Why does the speed of a planet decrease as it moves away from the Sun Brainly?
Why does the speed of a planet decrease as it moves away from the sun? the direction of the sun's pull relative to the planet's motion changes. Which statement about the development of Newton's theory of universal gravitation is correct?
Why do planets further away from the Sun take longer to orbit?
The size of an orbit is relative to the speed of the orbiting object. If a planet moved faster, it will be further, and completing a revolution will take longer because of the increased distance.
Which planet would be traveling at the slowest speed?
What is the Slowest Planet. Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe. If you walked along a bike path that circles its equator, you'd only need to go four miles an hour to keep night from ever falling on Venus.
At which location in its orbital path will a planet be moving the slowest?
aphelion A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).
Which planet moves around the Sun the 2nd fastest?
It speeds around the Sun every 88 days, traveling through space at nearly 29 miles (47 kilometers) per second, faster than any other planet. Mercury spins slowly on its axis and completes one rotation every 59 Earth days.
What is the second slowest planet in our solar system?

At what point does the planet move slowest?
aphelion A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).
Why Kepler’s 2nd law required that Earth goes slowest at aphelion?
This is because at every moment the planet spends on the perihelion half-ellipse it is closer to the Sun, moving faster; and at every moment it spends on the aphelion half-ellipse it is further from the Sun, moving slower.
When a planet is at its farthest point in orbit away from the Sun?
aphelion aphelion, in astronomy, the point in the orbit of a planet, comet, or other body most distant from the Sun. When Earth is at its aphelion in early July, it is about 4,800,000 km (3,000,000 miles) farther from the Sun than when at its perihelion in early January.
