Aphelion is the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
Mercury is the fastest planet in our solar system. It takes just 88 days to orbit around the sun at speeds of 50km per second.
Mercury is the planet in our solar system that orbits the sun at an average speed of about 170,500 kilometers per hour (at its fastest point).
The Earth-Sun Lagrange point L5 is located on the opposite side of the Sun from Earth, forming an equilateral triangle with Earth and the Sun. This point is approximately 1.5 million kilometers from Earth.
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.
The sun. Aphelion is the point in Earth's orbit where it is farthest from the sun.
At the point when it is closest to the sun.
Periapsis
the suns gravitational pull is strongest because the earth is at its closest point to the sun.
The Earth travels around the sun in an orbit that is in an elliptical (oval) shape. The sun is not in the center of the oval, but nearer to one end. The point in Earth's orbit when it is closest to the sun is called the perihelion, and that is also the point when the Earth is traveling fastest in its orbit. Where it is furthest from the sun (aphelion) is where it is traveling slowest.
The earth is moving fastest in its orbit at the moment of perihelion, when it is closest to the sun. the happens around January 3.
Mercury is the fastest planet in our solar system. It takes just 88 days to orbit around the sun at speeds of 50km per second.
In the winter It's when the earth is closest to the sun.
Mercury is the planet in our solar system that orbits the sun at an average speed of about 170,500 kilometers per hour (at its fastest point).
When it is closest to the Sun, on January 4th.
The Earth rotates. When wherever you are rotates to a point where the Sun is visible, that lights up your part of the world, and that's what we call Day.
The Earth-Sun Lagrange point L5 is located on the opposite side of the Sun from Earth, forming an equilateral triangle with Earth and the Sun. This point is approximately 1.5 million kilometers from Earth.
We call the closest point of approach to the Sun "perihelion". "Peri-" from the Greek for near, and "helion" from the Greek "Helios" or "Sun".At perihelion, the Earth is at a distance of 147,098,074 kilometers or 91,402,506 miles.
