This happens when earth is at perihelion, its closest approach to the sun, usually some time between January 2 and January 5. It does not happen at the solstice, December 21, as some think. The solstices are not lined up perfectly with aphelion and perihelion.

∙ 10y agoThe Earth's orbital velocity is greatest at the point in the orbit where we are closest to
the sun ... called "perihelion". The Earth is always at that point sometime during the first
few days of January.

Force: The only force present is the mutual gravitational attraction between the central body
and the orbiting object. It's well known that the gravitational force is greatest when the two
bodies are at their minimum separation, i.e. when the orbiting body is at the point in the orbit
that's closest to the central body.

Earth's orbital velocity is slowest on July 5 because?
On that date Earth is farthest away from the Sun.
Is it possible to run off the earth?
In theory, yes. You merely need to run at a little faster than orbital velocity at Earth's surface, and boom, there you are. This may prove a problem in practice, since orbital velocity at Earth's surface is about 5 miles per second.
What is the difference between orbital velocity and angular velocity?
Orbital Velocity is calculated in m/s where as angular velocity is calculated in rad/s.. Answer is very clear.. angular velocity is calculated when body is rotating around a axis and a reference point is needed to calculate it.. where as orbital velocity is calculated when body is moving around a bado in circular path, nt around itself... e.g. Earth rotates around so it have angular velocity .. it also rotates around sun in orbit so it has Orbital velocity also :)
What speed does the earth go to orbit the Sun?
The earth's mean orbital velocity is 18.5 miles (29.8 km) 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.
The velocity a rocket must reach to establish an orbit around earth is called?
Orbital velocity, or Close orbital velocity.
Which planet has the lowest orbital velocity?
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.
When is earth's orbital velocity the fastest?
perihelion
When is the earth orbital velocity the fastest?
perihelion
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 planet has the greatest orbital inclination orbit at the greatest angle to that of the Earth?
mercury has the greatest orbital inclination
What is the earth's greatest velocity?
perihelion
Which planets planetary orbits have the greatest inclination with respect to the plane of the ecliptic?
Pluto is the odd man out. -- Orbit with greatest eccentricity (0.249). -- Greatest orbital period (248 years). -- Lowest mean surface temperature ( -225 C ) -- Lowest mean orbital velocity (2.93 mi/sec) -- Smallest escape velocity (0.7 mi/sec, less than earth's moon) ==> Greatest inclination of orbit to the ecliptic: 17.2 degrees.

What is the value of orbital velocity?
the approximate value of orbital velocity is about 8km/hr.
