Which planet is 4 times as far from the sun as Earth?
Which planet is 4 times as far from the sun as Earth?
With a radius of 15,299.4 miles (24,622 kilometers), Neptune is about four times wider than Earth. If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun.
How do you find the average distance of a planet from the sun?
4. If an object is orbiting the Sun with an orbital period of 15 years, what is its average distance from the Sun? a = (225)1/3 = 6.1 AU….There is a simplified version of this law: P2 = a3 where:
- The object must be orbiting the Sun.
- P = period of the orbit in years.
- a = average distance of the object from the Sun in AU.
How does the period of a planet relate to its average distance from the sun?
Explanation: This is from the Law of Harmonies of Johannes Kepler which states that: The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. The more distant the planet is, the longer it will take for it to complete one revolution.
What would happen if the distance of a planet from the sun was doubled?
Doubling the distance from the sun reduces gravitational pull and increases the orbital period.
What is the distance from the Sun to its farthest planet?
The most distant planet in the Solar System is Neptune, which orbits the Sun at an average distance of 4.498 billion km (2.794 billion miles). Neptune was discovered by the German astronomer Johann Gottfried Galle on 23 September 1846.
How do we calculate the distance of the sun?
Aristarchus realized that when the Moon was exactly half illuminated, it formed a right triangle with the Earth and the Sun. Now knowing the distance between the Earth and the Moon, all he needed was the angle between the Moon and Sun at this moment to compute the distance of the Sun itself.
Why the distance from the Sun to a given planet is given as an average distance?
The closer the planet was to the Sun, the faster it moved. Conversely, farther planets orbited the Sun more slowly. Knowing this, he was able to connect the average distance of a planet from the Sun with the time it takes that planet to orbit the Sun once.
What would happen if the sun suddenly became a black hole?
What if the Sun turned into a black hole? The Sun will never turn into a black hole because it is not massive enough to explode. Instead, the Sun will become a dense stellar remnant called a white dwarf.
