It likes to have new scenery. Seeing the same thing all the time is boooring!

it changes because the sun loses mass continuously=R=GMs/V^2, Ms is the mass of the sun which changes continously.

Gravity.......................Mainly the Sun's Gravity.

Earth has a more or less steady and fixed orbit
But just like any Orbiting body, its path is usually slightly off centre, rather than eccentric
Earth's Moon has a Perigee and Apogee in its Orbit around Earth
Apex means Top, remember that
Earth, perturbed by other Planets Is heading towards its Perihelion on January 3rd 2020
Six Months Later, it will be at Apehelion
The Planet with the Least Eccentric orbit and also the lowest angle of Axis lean, 3 Degrees is the Most Massive Planet in our Solar System is of course Jupiter
After being formed first before Migrating outwards
Pluto has the most Eccentric Orbit and its whole System has an Axial Tilt of 90 Degrees
Like Uranus, it practically rolls around its Orbit
And Only lost its Planetary Status because of other Bodies in the Kuiper BeltSource(s): New Horizons, Pluto and Charon

Many reasons... the sun is actually losing mass as it ages, and our orbit expands a tiny bit. The position of Venus, Mars, and Jupiter also affect Earth's orbit, tugging on Earth a tiny bit as they pass by us or we pass by them. Then, there's the cumulative effects of impacts by in-falling meteors; over the course of a year, there's usually slightly more hitting us on our leading edge than our trailing edge.

The earth's orbit is stable and does not change, at least not on any human time scales. But in that stability are many influences (the moon, the other planets, the eccentricity of the orbit, the dynamics of the spinning earth among them) that create predictable, plottable variation. Over millions, billions of years those variations will add up to real change over the orbit we see now. But nothing changes the orbit to any significant degree within the span of human existence.

it doesn't, to any significant degree. Any changes are tiny, and are due to the gravitational influences of the other planets, and by tidal effects of the sun.
