because of gravitational forces, also so we can have seasons on the Earth and a changing temperature.
the Earth rotates on an axis, that axis is tilted with respect to the axis of Earth's orbit, and Earth's orbit is slightly elliptical.
The Earth stays in orbit around its axis due to its rotation and inertia. The gravitational pull of the Sun keeps the Earth in its orbit, while its rotation on its axis causes day and night. The tilt of the Earth's axis also plays a role in the changing seasons.
The tilt of the Earth's axis in relation to the plane of its orbit.
The major axis of Pluto's orbit, which is its semi-major axis, is approximately 5.9 billion kilometers (3.7 billion miles), while Earth's semi-major axis is about 150 million kilometers (93 million miles). This means Pluto's orbit is significantly longer, roughly 39 times the length of Earth's orbit.
No. Earth's orbit is NOT tilted. Earth orbits the Sun in the same plane as the rest of the planets. What IS tilted is Earth's axis of spin (as compared to the plane of its orbit), It is this tilt of this axis that causes the seasons as Earth makes its annual orbit of the Sun.
Earth takes approximately 24 hours to complete one full rotation on its own axis. This rotation is what causes day and night on Earth.
Earth's axis tilts at very close to 23.5 degrees.
It depends if it is an orbit around it's axis or an orbit around the sun. Heres the answer for both: Sun Orbit: 687 Earth Days Axis Orbit: 687 Earth Days The funny thing is that their both still the same :)
The tilt of the earth's axis, and because of the earth's orbit.
0 days 9 hours 56 minutes in Earth Time by the way it is a complete rotation on its axis, not to orbit on its axis.
The Earth's axis is tilted about 23 degrees.
It does NOT orbit on its axis, but rotates on its axis. It takes 24 hours, one day, to make one complete rotation. However, It does ORBIT the Sun. It takes the Earth 365.25 days, one year, for make one complete orbit of the Sun. Whilst it is making this orbit it is also rotating on its axis, as above.
