2 January 2021 is closer to EarthIn its elliptical orbit, compared to any day of the year, there is an annual event known as perihelion.
The term perihelion is translated from ancient Greek, meaning “near the sun.” Due to this EarthSky, the Earth was scheduled to arrive at 20:51 Eastern time on Saturday morning.
On Saturday, the sky is about 3% larger – it is not enough to be visible to the naked eye. Remember: You should never look at the sun without proper protection, and sunglasses are not an adequate substitute for sunglasses.
Earth’s orbit is not a full circle, which means that sometimes the planet is slightly closer than our star and sometimes it is far away. This distance changes about 3 million miles during the year – about 13 times the Moon’s distance from Earth.
Perihelion also refers to the moment the Earth moves in its orbit around the Sun at the highest speed. The planet currently orbits the Sun at 19 miles per second – about 6 miles per second when it reaches its farthest point from the Sun in July.
“If you run eastward at midnight, you’ll move as fast as possible (minimum coordinates centered on the Sun)” to your position, “NASA said.
For this reason, summer in the Northern Hemisphere lasts about five days longer than winter. EarthSky. The opposite is true in the Southern Hemisphere.
Although sunlight is more intense on Saturday, the 23.5 degree tilt of the Earth’s axis does not affect winter in the Northern Hemisphere. Being closer to the sun will not change the tilt of the Earth, so the North Pole is still away from the sun.
In six months, on July 5, the Earth will be farthest from the Sun, known as its apathy, which means “away from the Sun.” In the perihelion, the Earth is about 91.5 million miles from the Sun, and in the afternoon it is about 94.5 million miles away.
Between the perihelion and the aphelium, there is about 6.7% difference in the intensity of sunlight in a collision with our planet. According to NASA, this is an explanation for more extreme periods in the Southern Hemisphere than in the Northern Hemisphere.
Perihelion is not the only astronomical event this weekend. Sunday, sunday and sunday morning peak– One of the best of the year.
