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 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.
What is earth inclination?
Earths orbital inclination is 1.57869°
Another name for the earths orbital period?
The year.
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
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.

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
Which planet has an orbital eccentricity most like the orbital eccentricity of the earth?
The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859
What means the tilt of the earths axis?
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs from orbital inclination.
What is the action of the spacecraft leaving the earth called?
escape velocity if its leaving earths gravity
