Basically, like everyone else, astronomers hate large numbers.
Why say 93,000,000 miles or 9.3 x 107 or to keep the Europeans happy, 150,000,000 kilometers or 1.5 x 108 when all they need to say is an AU.
The average distance from the Earth to Sun is a known constant amongst the professional and amateurs alike, even school children can. Why would they choose an obscure distance like Neptune or Venus.
It's the same reason all stellar descriptions are based on a known entity - our Sun.
Stars are classified as x solar masses or x solar radii.

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.
What unit is used to measure distance outside Earths solar system?
Light years
What is solar constant and their formula?
The solar constant is the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere in a plane perpendicular to the rays. See link for formula
Does solar constant affect temperature?
Yes, the solar constant affects temperature by determining the amount of solar energy reaching the Earth's atmosphere. A higher solar constant can lead to an increase in temperature, while a lower solar constant can result in cooler temperatures.
Is Pluto smaller the Earths moons?
Yes as Pluto is the smallest and the last planet in the solar system, it is smaller then the earths moons.
What will be the distance in international system of solar system?
A "distance" must be specified between two objects. There is no "distance of the Solar System" by itself.
What is the solar constant formula used to calculate the amount of solar energy received at the outer atmosphere of Earth?
The solar constant formula is used to calculate the amount of solar energy received at the outer atmosphere of Earth. It is represented by the equation: Solar Constant Solar Irradiance / Distance from the Sun squared.
What unit is used to measure distance outside Earths solar system?
Light years
What year earths gravitational constant invented?
The earth's gravitational constant was created about 4.5 billion years ago, with the formation of the planet within the Solar System.
What is solar constant and their formula?
The solar constant is the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere in a plane perpendicular to the rays. See link for formula
Calculate the solar constant if the earth to sun was 10 AU?
The density of radiation per unit area is inversely proportional to the square of the distance from the source. Trust me on this. So if the distance from the sun increased by a factor of 10, the present solar constant would decrease by a factor of 102 = 100.
What is meant by the term solar constant?
The solar constant refers to the amount of solar energy received per unit area at the top of Earth's atmosphere when the Sun is directly overhead, measured at a distance of one astronomical unit (the average distance from the Earth to the Sun). It is approximately 1,361 watts per square meter. This value can vary slightly due to solar activity and Earth's orbital changes, but it provides a baseline for understanding solar energy input to the Earth.
Does solar constant affect temperature?
Yes, the solar constant affects temperature by determining the amount of solar energy reaching the Earth's atmosphere. A higher solar constant can lead to an increase in temperature, while a lower solar constant can result in cooler temperatures.
What is the solar constant a measure of?
The solar constant is a measure of the amount of solar radiation received per unit area at the outer atmosphere of the Earth. It represents the average solar power per unit area that is received on Earth's surface on a clear day.
What is the solar distance of the sun?
The solar distance is 3.5689.
Is solar constant actually a constant?
its fairly constant,increasing only 0.2% at the peak of each 11 year solar cycle.
What is earths position in the solar system according to its size?
Of the eight planets in our solar system, Earths is the fifth largest or the fourth smallest.
