What is Aphelion?

Aphelion is a moment at the point of dressing the celestial body around the sun when the heavenly body is the farthest of the sun. The opposite of Aphelion is Perihelion when this object is closest to the sun. Each of the objects orbiting the Sun is experiencing Aphelion and Perihelion at different time points, and the difference between these two points may vary radically, depending on the eccentricity of the object's orbit. in his first law. The amount of scattering from a perfectly circular orbit is known as the "eccentricity" of orbit. The higher the eccentricity, the more elliptical the orbit. The Earth has relatively low eccentricity, around 0.0167, unlike mercury, with an eccentricity of 0.2056.

In the case of Earth, Aphelion falls in the northern hemisphere, around July. The accurate timing of Aphelion is around 30 minutes every year after 21,000 years, which means that Aphelion will fall for the country in the summer of the southern hemisphere. Although the Earth is during Aphelion at the farthest point of the sun, the planet is the hottest in the summer in the summerThe velocity of the hemisphere, because the large ground masses in the northern hemisphere warm up and distribute their heat on the planet.

In Perihelion, the Earth is approximately 91 million miles (147 million kilometers) from the Sun, unlike 95 million miles (152 million kilometers) from Aphelion. This variation from the distance is relatively small compared to the orbits of the two other objects orbiting the sun. For example, Pluto has a very elliptical orbit with an extreme variation between Cztrat and far. The distance of Pluto from the Sun is measured in astronomical units (AU), each au representing the average distance between the sun and the earth: in Perihelion, Pluto is 30 times further (30 AU) from the Sun than Earth and Afelion, Pluto is 49 times further (49 AU) from there.

Astronomers can use a range of formulas to calculate distances of different objects from the Sun at different points of their orbit and can also map the paths that willWhen moving around the sun, watching countless objects. Numerous graphs showing orbit planets and their close and distant points can be found in the atlas and scientific texts.
