Perihelion and Aphelion are used to describe the minimum and maximum distances that a planet will be from the sun. The earths perihelion (minimum distance) is around 91.4 million miles in January, while its aphelion is around 94.5 million miles in July. These terms are only used for bodies in direct orbit around our sun, different terms are used to describe moons, and other bodies that are in orbit around something else.

Is the perihelion a solar or subsolar point?
"Perihelion" is a place in space, not on the earth. It's the point in the orbit of any member of the solar system where the orbiting object is closest to the sun. Earth reaches its perihelion each year during the first few days of January. In 2010, it was in the 7 PM hour EST on January 2.
What is the distance from the sun to the fourth planet in your solar system?
The fourth planet from the sun is Mars. Aphelion is 249,209,300 km. Perihelion is 206,669,000 km
What is the point that is closed to the sun in the orbit of a planet?
The point closest to the Sun in the orbit of a planet is called perihelion. At perihelion, the planet is at its minimum distance from the Sun, leading to increased solar radiation and gravitational pull. This point varies for different planets within the solar system, depending on their elliptical orbits.
How do you calculate the value of the solar constant on mercury at perihelion?
To calculate the solar constant on Mercury at perihelion, you first need to determine the distance between Mercury and the Sun at that point, which is approximately 57.91 million kilometers. The solar constant is calculated using the formula ( S = \frac{L}{4\pi d^2} ), where ( L ) is the solar luminosity (about ( 3.828 \times 10^{26} ) watts) and ( d ) is the distance from the Sun in meters. By substituting the perihelion distance into the formula, you can find the solar constant value at that distance. At perihelion, the solar constant on Mercury is approximately 91,600 watts per square meter.

Describe earth's position in relation to the sun at perihelion?
in relation to earth the sun is in the center of our solar system and we revolve around the sun
Can you consider that the planets in your solar system as having elliptical orbits with the same major axis and the perihelion and aphelion on the same side on this axis?
NO. jus...just no. Although I did see an alien with a sharpie in his pooper once.
What is perihelim?
The term "perihelion" refers to the point in its orbit when a planet or other celestial body is closest to the Sun. This creates a situation where the body experiences its maximum gravitational acceleration from the Sun, which can affect its motion and orbit.
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.
Where is haumea located in the solar system?
Haumea is one of the newly-discovered Kuiper Belt Objects out beyond the orbit of Neptune. It has a perihelion distance of about 35 AU.
How big is the solar system from the sun to Pluto?
Pluto is closer than Neptune at perihelion. At aphelion its orbit is approximately 50 AU. If we use that as the radius of the solar system, then our solar system is 100 AU across. In terms of light, it takes 8.3 minutes for sunlight to strike earth. The solar system's diameter would therefore be 830 light minutes, or 13.8 hours. Our solar system extends far beyond Pluto, however. Eris is nearly 100 AU at aphelion. As the largest known Kuiper belt object (bigger than Pluto/Charon), it is still MUCH closer than any Oort Cloud object.
Where does Halley's Comet spend most of its time?
Halley's Comet spends most of its time in the outer regions of the solar system, specifically in the Kuiper Belt and the Oort Cloud. It has an elongated orbit that takes about 76 years to complete, bringing it close to the Sun and Earth during its perihelion. During its long journey, it remains far from the inner solar system for the majority of its orbit.
