"The first part of the word, 'sol', means sun and the suffix means 'to stop’. On the Summer Solstice, the sun appears to stop rising in the sky because it has reached its highest point", said Natural Science Professor Don Wheeler, from Louisiana Delta Community College.

It has been told by Wheeler and colleagues that Wednesday would be the day of Summer Solstice, which means the longest day of the year.

The day is seen two times a year, when sun reaches its peak point and is at the farthest distance from the equator. However, it is believed that change in seasons occur because of the proximity of the Earth.

But, as per the team, it is actually due to changing position of the sun. The change in its position is caused by Earth’s rotation in an ellipse, an oval-shaped path, around the Sun.

The sun remains in front of the North Pole for the first half of every year, while for the second half, it is faced by the South Pole.

Though Sun is closer to the planet during the first day of winter, it is the summer’s first day when northern hemisphere directly confronts the star, the report concludes.
