Morphology (astronomy) is the shape of an astronomical object, like nebulae, galaxies, or other extended objects.

This is Schelling's "absolute identity": the ideas or mental images in the mind are identical to the extended objects which are external to the mind.

The total magnitude is a measure of the brightness of an extended object such as a nebula, cluster or galaxy.

So the ideas or mental images in the mind are identical to the extended objects which are external to the mind.

Since the coaster is an extended object and not a point, the math exceeds that which is taught in high schools.

Classical mechanics also includes descriptions of the complex motions of extended non-pointlike objects.

If an object is three-dimensional, then it is an extended object.

Observations are also planned of extended objects.

The aggregate is semantically an extended object that is treated as a unit in many operations,although physically it is made of several lesser objects.

A central velocity dispersion refers to the σ of the interior regions of an extended object, such as a galaxy or cluster.
