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.

What is the name for a planet's speed in its orbit?
It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."
What is Orbital Speed?
The orbital speed of a planet is a direct result of the gravitational force between that planet and the Sun. The greater the force, the faster the speed.
What speed does a rocket have to reach to get into space?
(Escape velocity) at least 7 miles ber second. Close-Orbital velocity is about 5 miles per second.
Explain What is the Orbital Energy and what is the Escape Velocity?
Orbital energy is that amount of energy to keep a spacecraft or satellite in orbit around the earth. If the object fails to maintain this amount of energy, its orbit will get smaller and smaller until the object falls to earth. Escape velocity is that amount of speed required for an object to escape the earth's gravitational hold. Notice how you can't jump into outer space. It's because your legs can't produce enough power to achieve escape velocity.
The average orbital velocity of the earth is about 66000 miles per hour?
Earth's orbital velocity is about 30 kilometers per second. That should be approximately the speed you mention in the question.Earth's orbital velocity is about 30 kilometers per second.

Which term refers to the speed at which a planet travel in its orbit?
Orbital velocity refers to the speed at which a planet travels in its orbit.
What does the words orbital speed mean?
Orbital speed is the velocity (speed) of an object as it travels an orbital path around a reference point.
What is the name for a planet's speed in its orbit?
It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."
Do mercury and earth travel at the same speed?
Nope. Mercury has an orbital velocity of 47.9km/s, whereas Earth has an orbital velocity of 29.8km/s.
What is the speed of Jupiter planet?
Jupiter has an orbital velocity of 13.1km/s.
What is planetary velocity?
Orbital velocity is the average velocity (or speed) of a planet as it orbits around the sun. It is usually expressed as km/s or mph.
What does it mean orbital speed?
The velocity a planet travels in it's circle around the Sun
What are difference between speed and velocity?
Velocity is speed with direction
What is the biggest difference between speed and velocity?
velocity is speed with direction; velocity is a vector and speed is a scalar
The orbital speed of Venus' and Neptune?
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
What is the diffrance between speed and velocity?
Speed is magnitude of velocity, also velocity possess direction.
What is Orbital Speed?
The orbital speed of a planet is a direct result of the gravitational force between that planet and the Sun. The greater the force, the faster the speed.
