Earth's orbital velocity is greatest during the Northern Hemisphere's winter, specifically around early January, when Earth is closest to the Sun in a position called perihelion. This increased speed occurs due to the gravitational pull of the Sun being stronger when the distance is shorter. Conversely, during the summer in the Northern Hemisphere, around early July, Earth is farthest from the Sun (aphelion) and moves more slowly in its orbit.
What else can I help you with?
Between what seasons does orbital velocity speed up and slow down?
The season depends on which hemisphere you are in.The earth's orbit around the sun is not a circle. The earth's orbit around the sun is slightly elliptical. Therefore, the distance between the earth and the sun varies throughout the year.At its nearest point on the ellipse that is the earth's orbit around the sun, the earth is 91,445,000 miles (147,166,462 km) from the sun. This point in the earth's orbit is known as perihelion and it occurs on January 3. During our closest approach is when our orbital velocity is the greatest.The earth is farthest away from the sun on July 4 when it is 94,555,000 miles (152,171,522 km) from the sun. This point in the earth's orbit is called aphelion.The slight ellipse in the earth's orbit does have a slight impact on the amount of solar energy being received by the earth. This 3.3% difference in distance does not impact the earth as much as the seasonal variations, however.From: http://geography.about.com/od/physicalgeography/a/orbitsun.htm
During which season in the northern hemisphere does the earth reach its greatest distance from the sun?
The Earth reaches its greatest distance from the Sun during the summer season in the Northern Hemisphere. Though it may seem counterintuitive, the distance between the Earth and the Sun varies due to the elliptical shape of Earth's orbit, with the Earth being farthest from the Sun during the summer months.
What will happen if the earth's axis remains parallel to itself all around the orbit?
If the equatorial plane were perpendicular to the orbital plane, there would be dramatic seasons. At the solstices, everything on the side of the equator facing the sun would receive 24 hours of daylight, and the other side would have 24 hours of night. At the equinoxes, the entire earth would have 12 hours of day and 12 hours of night. I think you may have meant to ask about what would happen if the equatorial plane were PARALLEL to the orbital plane. If this were the case, there would be no seasons. Every point on Earth (other than the poles) would have 12 hours of day and 12 hours of night at all times. The poles would experience permanent twilight.

Where do the Suns rays hit Earths surface nearly at right angles?
The Sun's rays can hit Earth's surface at a right angle to the surface, depending on the season, anywhere between the tropics (i.e., between 23.5 degrees north and 23.5 degrees south), at noon, when the Sun is highest in the sky.
When Earth is closer to the Sun during the year what season is it?
When Earth is closer to the Sun, it is in winter in the Northern Hemisphere and summer in the Southern Hemisphere. The distance between Earth and the Sun (known as Earth's orbital distance) doesn't significantly affect the seasons; the tilt of Earth's axis is the primary factor that determines the seasons.
Does the earths orbit changes the season?
No. Earth's orbital eccentricity (a measurement of the difference between the closest and farthest approach of the Earth to the Sun) has negligible effect on seasonal changes. Rather it's earth's axial tilt that gives rise to seasons.
Are the season caused by the tilt of the earths axis?
Yes.
What season is it when the sun is heating earths surface the most?
It is summer when the sun is heating earths surface the most.
What does a solstice look like?
Solstice is the seasons in a month's season's weather changes because the solstice changes such as every 24 of March and December. Solstice in earths orbit at which the hours of daylight are their greatest or fewest.
