Why is the earths orbital velocity fastest at perihelion?
the suns gravitational pull is strongest because the earth is at its closest point to the sun.
A picture of earths orbital path?
elliptical.
Another name for the earths orbital period?
The year.
How much does earths orbit around the sun vary throughout the year?
Aphelion is 152,098,232 km (the distance when the Earth is furthest from the Sun in July) at that point it is moving slowest: 29,300 m/s. Perihelion is 147,098,290 km (in January when the Earth is closest to the Sun) the orbital speed is greatest: 30,300 m/s.
What is the slowest to change earths surface?
The slowest-changing feature on Earth's surface is likely its tectonic plates, which move at a rate of a few centimeters per year. This movement can result in slow changes in topography and the creation of mountains or ocean basins over millions of years.
Why is Earths orbital velocity slowest on July 5?
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.
Why is the Earths orbital velocity is the slowest on July 5 because?
The Earth's orbital velocity is slowest around July 5 due to its position in relation to the Sun during the aphelion, which occurs when the Earth is farthest from the Sun. According to Kepler's laws of planetary motion, a planet moves slower in its orbit when it is farther from the Sun. Consequently, this increased distance results in a decrease in orbital speed, making July 5 the date when the Earth travels at its slowest velocity.

What is earth inclination?
Earths orbital inclination is 1.57869°

How does the sun's gravity and the earth's gravity affect each other?
they pull toward each other, but the earths orbital velocity compensates exactly for this acceleration together due to gravity a = (G* (m1+m2))/d^2 acceleration that balances this a = v^2/d : G = newtons gravitational constant m1 = sun mass m2 = earth mass d = distance between centres v = orbital velocity
How would the speed of Earths orbit around the sun change if Earths distance from the sun increased by 4 times?
If Earth's distance from the Sun increased by four times, its orbital speed would decrease significantly. According to Kepler's Third Law of Planetary Motion, the square of the orbital period is proportional to the cube of the semi-major axis of the orbit. Therefore, with an increased distance, Earth would take longer to complete an orbit, resulting in a slower speed, roughly one-half of its current average orbital velocity.
Why must a horizontally moving projectile have a large speed to become an earth's satellite?
At lower speed, the object will fall back on the ground. Since, earth is curved, if the object has enought speed, the object can try to fall beyond the curvature of the earth. Thus, it will not hit ground at all. The speed to achieve it is around 8 km/s. If the object is faster than 11.4 km/s then the object will never return. It is called escape velocity.
What season is earths orbital velocity greatest?
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.
How much does earths orbit around the sun vary throughout the year?
Aphelion is 152,098,232 km (the distance when the Earth is furthest from the Sun in July) at that point it is moving slowest: 29,300 m/s. Perihelion is 147,098,290 km (in January when the Earth is closest to the Sun) the orbital speed is greatest: 30,300 m/s.
Why do earth and the moon remain in their orbits?
(simplified) Gravitational force of attraction is balanced by centripital force due to earths velocity. (G*m1*m2) / r2 = m2 * (v2 / r) m1 = sun mass m2 = earth mass r = earth - sun distance v = earths orbital velocity G = newtons gravitational constant
