There are far more than two objects in orbit since the first Sputnik. If the question refers to only natural objects, there is a body sometimes called "Earth's second Moon" but it's not; it merely has its own orbit around the Sun close to the Earth's.
27 1/2 days.
27 1/2 days for both.
you have to hold control and then just move your mouse around and it will spin
About 27 1/2 days in both cases.

In one revolution around our Sun, the Earth rotates just over 365 times. In 4 revolutions around the Sun, the Earth rotates about 1461 times. The average year for the Earth is about 365.25 days.
Clarification of terms: the Moon ROTATES around its own axis; it REVOLVES around the Earth. Both things - one rotation and one revolution - take about 27 1/2 days.
The Earth's path around the Sun is elliptical, and the Earth's speed around that path varies a little; faster when we're closest (around January 4) and more slowly when we're farthest away (around July 2). But the difference is only around 3%. On average, the Earth is moving a little over 66,600 miles per hour in its path around the Sun.
spin is the symmetry of something, if it has a spin of 1, then you need to rotate the thing 1 full circle for it to look the same as when you didn't rotate it. if it has a spin of 1/2, then you need to rotate it 1/2 of a circle. it is actually possible for something to have a spin of 2 (2 full circles) or higher.

The five motions of the earth are 1. Axial rotation 2. Lunar co-orbital (Earth and Moon rotate around a central point together) 3. Solar orbital 4. Procession (the axis of the Earth wobbling) 5. Galactic (the Solar system orbits around the Milky Way galaxy)
