The orbit of a planet is not a circle with the sun at the center. It's an ellipse with
the sun at one focus.
An ellipse is an 'egg shape', or 'oval', or 'squashed circle'. It has two foci (focuses)
and neither one is in the center.
So you can easily see that as the planet moves along the ellipse, its distance from the sun
changes, and there is a minimum distance (perihelion) and a maximum distance (aphelion).
Those don't change unless the shape of the ellipse changes, and the only way
that happens is through the gravitational influence of the other planets, which
is relatively tiny over the course of many millennia.

What two factors affect a planets revolution?
Two factors that affect a planets revolution are distance from the sun and size.
What two factors will affect gravitational attraction?
Mass and distance. The force decreases with the square of the distance, so mass has a lesser effect on the equation.
What factors would affect the length of the day?
The length of the day would change if either the rotational speed of the the planet or the orbital distance from the sun changed. However, if you mean what factors affect the length of daylight, then that is different.
What are the two factors that affect the gravitational pull of a palnet?
Gravity is the attraction between two or more bodies. It is propotional to their mass and inversely proportional to their distance.
What are the two main factors that affect gravity?
The two main factors that affect gravity are mass and distance. The gravitational force between two objects increases with their mass; the larger the mass, the stronger the gravitational pull. Conversely, the gravitational force decreases with increasing distance; as the distance between two objects increases, the gravitational attraction diminishes. This relationship is described by Newton's law of universal gravitation.
How does the distance between Earth and the Sun during aphelion and perihelion affect temperature on our planet?
The distance between Earth and the Sun during aphelion and perihelion affects the temperature on our planet because when Earth is at aphelion (farthest from the Sun), it receives less solar energy, leading to slightly cooler temperatures. Conversely, when Earth is at perihelion (closest to the Sun), it receives more solar energy, resulting in slightly warmer temperatures.
What is the relationship aphelion and perihelion to season?
Perihelion and aphelion have no relationship to the seasons, although they do occurat the same time each year.If you're thinking that the Summer's heat and the Winter's cold are somehow relatedto the Earth's distance from the sun, you need to be reminded that when it's Summerin your hemisphere, it's Winter in the other one. On exactly the same day !And as for the US, Canada, Mexico, Europe, Russia, and everybody else in the northernHemisphere, we are closest to the sun right in the middle of our Winter, in the first fewdays of January.
What are to factors that affect gravity?
Mass, distance.
What factors affect the weather is?
the three factors that affect the weather are altitude the distance from the ocean and topagraphy! ***hopefully this helped you!
What two factors affect a planets revolution?
Two factors that affect a planets revolution are distance from the sun and size.
What are the two factors that affect gravity?
mass and distance ;)
What 2 factors affect gravitational force?
The two factors that affect gravitational force are the mass of the objects and the distance between them. Gravitational force increases with the mass of the objects and decreases with the distance between them.
2 factors that affect reaction distance and braking distance?
i dont know maybe you guys do.
What are to factors that affect the rate of weathering?
distance from the sea, ocean current
What are the 2 things affect speed?
The two main factors that affect speed are distance and time. Speed is calculated by dividing the distance traveled by the time taken to travel that distance.
What are the factors affecting solar cell output?
If you're talking about the whole Earth, there are not many that affect the amount of energy. One factor is in the distance of the Earth from the Sun. The Earth gets slightly more energy from the Sun at the Perihelion (the closest point to the Sun) than the Aphelion (the furthest point away from the Sun). Another factor is how active the Sun is. The Earth is likely to receive less energy from the Sun at a solar minimum than a solar maximum in the 11 year cycle of the Sun (because the Sun is outputting less energy).
What do the two factors affect the forces of gravity?
The two main factors that affect the force of gravity between two objects are the mass of the objects and the distance between them. The force of gravity increases with the mass of the objects and decreases with the distance between them.
