orbit
The path is called an "orbit", and it has the shape of an ellipse, the Sun being at one focus of the ellipse.
An orbit.
The curved path of a planet around the sun is called an orbit. Orbits are elliptical in shape, with the sun located at one of the foci of the ellipse. The gravitational pull of the sun keeps the planet in its orbit as it travels around the sun.

orbit
Inertia is trying to keep each planet moving in a straight line, and the sun's gravity is trying to pull each planet into the sun. The resultant of those two vectors is the orbital path each planet follows.

The Arctic Tern migrates around 22,000 miles each year.
Because they each have a certain path that they follow, and the paths do not intersect.
A double planet describes two bodies of similar size and mass that are in orbit (not necessarily around each other) . The Earth and Moon would not be considered a double planet because of the great size and mass difference between the two. However, Pluto and its moon Charon COULD be classified as a double planet- both have similar sizes and mass, and orbit a point outside of one another.
Yes, gravity pulls a spacecraft towards the nearest planet because objects with mass attract each other. The gravitational force between the spacecraft and the planet causes the spacecraft to be pulled towards the planet as it travels through space.
