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.
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.
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 :)
On that date Earth is farthest away from the Sun.
Earth's average orbital velocity around the Sun is about 29.78 km/s, while Mercury, being closer to the Sun, has a higher average orbital velocity of approximately 47.87 km/s. This difference is primarily due to Kepler's laws of planetary motion, which state that planets closer to the Sun travel faster in their orbits. As a result, Mercury orbits the Sun more quickly than Earth.
The orbital velocity of Earth follows a cyclic pattern primarily due to its elliptical orbit around the Sun, as described by Kepler's laws of planetary motion. This means that Earth moves faster when it is closer to the Sun (perihelion) and slower when it is farther away (aphelion). Additionally, the gravitational interactions with other celestial bodies, such as the Moon and other planets, can slightly affect Earth's velocity, contributing to variations over time. These factors combine to create a predictable cycle in Earth's orbital speed.
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.
The orbital velocity of an object depends on its distance from the center of mass it is orbiting. For example, the orbital velocity of the Moon around Earth is about 1 km/s, while the orbital velocity of the International Space Station (ISS) around Earth is about 8 km/s.

Nope. Mercury has an orbital velocity of 47.9km/s, whereas Earth has an orbital velocity of 29.8km/s.
The velocity a rocket must reach to establish an orbit around the Earth is called orbital velocity. It is the speed required for an object to overcome gravitational pull and maintain a stable orbit around the planet. The orbital velocity depends on the altitude of the orbit and follows Kepler's laws of planetary motion.

mercury has the greatest orbital inclination
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.
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.
Earth's orbital velocity is slowest on July 5 because that is when Earth is at aphelion, its farthest point from the Sun in its elliptical orbit. At this point, the gravitational pull from the Sun is weaker, causing Earth to move more slowly in its orbit.
