When the Earth is at perihelion?

The Earth is closest to the Sun, or at the perihelion, about 2 weeks after the December Solstice, when it is winter in the Northern Hemisphere. Conversely, the Earth is farthest away from the Sun, at the aphelion point, 2 weeks after the June Solstice, when the Northern Hemisphere is enjoying warm summer months.

Then, what is the perihelion and aphelion?

When the planet is furthest away from the Sun, it is at aphelion. The words "aphelion" and "perihelion" come from the Greek language. In Greek, "helios" mean Sun, "peri" means near, and "apo" means away from. When Earth is at perihelion, it is about 147 million km (91 million miles) from the Sun.

What is perihelion condition of Earth?

The perihelion is the point in the orbit of a planet, asteroid or comet that is nearest to the sun. It is the opposite of aphelion, which is the point farthest from the sun. (The similar word, perigee, refers to the nearest point in some object's orbit of earth.)

When the Earth is at aphelion?

Bottom line: Planet Earth reaches its most distant point from the sun for 2018 on July 6. Astronomers call this yearly point in Earth's orbit our aphelion.
