What is solar constant and their formula?
The solar constant is the amount of solar electromagnetic radiation received per unit area on a surface perpendicular to the Sun's rays at a distance of one astronomical unit (AU). The approximate value of the solar constant is 1361 watts per square meter. The formula to calculate it is: Solar Constant = Solar Luminosity / (4πAU^2).
What number of planets does mercury have in its solar system?
Mercury is a planet in our solar system, not a solar system itself. Our solar system has eight planets, and Mercury is the closest planet to the sun.
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.
In your solar system which planet is closest to the sun?
Mercury is the closest planet to the sun in our solar system.
Why does temperatures on mercury vary so much?
Mercury is the closest planet to the Sun and it also has a very eccentric orbit. At its perihelion it is only 46 million km from the Sun - compared to 147 million for the Earth. The intensity of solar radiation (across the whole spectrum) is 4.6 to 10.6 times that on Earth. Furthermore, Mercury has no significant atmosphere to redistribute the heat from the insolation. As a result temperatures at perihelion, in direct sunlight reaches 700 K. Meanwhile, the near-absence of an atmosphere allows the heat to be radiated away into space at night so that temperatures drop to 80 K.

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 solar system is mercury in?
Mercury is in the same solar system that we are in.
What number of planets does mercury have in its solar system?
Mercury is a planet in our solar system, not a solar system itself. Our solar system has eight planets, and Mercury is the closest planet to the sun.

What is the solar constant at Mars?
The solar constant at Mars is about 590 W/m^2, which is lower than at Earth due to its farther distance from the Sun and its thinner atmosphere. This value represents the amount of solar energy received per unit area at the top of Mars' atmosphere.
In your solar system which planet is closest to the sun?
Mercury is the closest planet to the sun in our solar system.

What is work of mercury in solar system?
Mercury is the smallest planet in our solar system excluding Pluto.
What is the galaxy of mercury?
Mercury is part of the Solar System, the Solar System is part of the Milky Way; ergo, Mercury is in the Milky Way.
Does Jupiter and mercury have stars in their solar system?
Jupiter and Mercury are in the same solar system that we are. That solar system has 1 star: the sun.
