Can elliptical and the ecliptic orbits be classified as inclined orbits since their eccentricity is not zero(They are not directly above the equator)?

These are two relatively unrelated parameters of an object's orbit. The eccentricity of the orbit represents how close to circular it is (e = 0 is a perfect circle; e < 1 is an ellipse; e = 1 is a parabola; e > 1 is a hyperbola).

The inclination of the orbit represents the angle between the object's orbit and the "equatorial plane" defined for the particular system. In talking about objects orbiting the earth, we use the equatorial plane as the reference. In talking about the earth's orbit around the sun, we speak of the "ecliptic" which is the plane of the earth's orbit. In speaking of other objects' orbit about the sun, we can use either the solar equator or the mean planetary ecliptic (which is defined as the plan perpendicular to the sum total rotational inertia vector of all objects in solar orbit, defined mostly by the mass of Jupiter, as Jupiter represents about 72% of the planetary mass of the solar system). Relative to this definition, earth's orbit has an inclination of about 1.5 deg.

The ecliptic is the sun's path through the star background over the course of a year. An orbit can be in the ecliptic (in the plane of the earth's orbit around the sun) and still have non-zero eccentricity (be elliptical). An inclined orbit can be circular (zero eccentricity); its orbital plane would be at an angle to the earth's.

An elliptical orbit can be obtained and maintained that *does* follow the equator, so you really can't classify such an orbit as eccentric in those terms. However, in relation to a perfect spherical orbit an elliptical one is eccentric. Ecliptic orbits are of course eccentric relative to the equator.

definite it could. The orbit ellipse lies in a airplane properly-known because of the fact the orbital airplane. The orbital airplane continuously is going interior the direction of the midsection of the earth (or different important physique), yet may well be tilted any perspective relative to the equator. the actuality that the orbit inclination (23°26') is the comparable because of the fact the perspective of the ecliptic would not remember. Any (Keplerian) orbit is defined by using seven numbers. normally, those used are: epoch, orbital Inclination, good ascension of ascending node, argument of perigee, eccentricity, recommend action, and recommend anomaly.

No. Elliptical and inclined mean totally different things.
Elliptical means the orbit is not always at the same altitude. It may or may not always be directly above the equator.
Inclined means it is not always above the equator. It may or may not always be at the same altitude.
So an orbit could be one of 4 things:

circular and not inclined
or
circular and inclined
or
elliptical and inclined
or
elliptical and not inclined

No inclined orbit are the one whose orbital plane is not coplanar with earth-sun orbital plane. Elliptical orbits are the one that have different distance to its primary over the revolutionary period.
