It is the period of time during which the earth makes one complete revolution on its axis

It is a hypothetical whirling gaseous mass within a giant cloud of gas and dust that rotates around a sun and is believed to give rise to a planet

It suggests that a huge tidal wave, raised on the sun by a passing star, was drawn into a long filament and became detached from the principal mass.

It is when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. This material is gradually pulled together by gravity to form small chunks.

It is the property of any rotating object given by moment of inertia times angular velocity.

The origin of the solar system, involving the approach near the Sun of another star. This set up tidal forces, and the instability of the Sun resulted in part of its mass being torn off to form the planets.

2. It describes the universe as originating from infinitely tiny, dense point or singularity around 13-14 Ga (gigaannum or billion years ago)

3. It presumes that the Solar System began as a cloud of dispersed interstellar gas or cloud of dust.

4. It is the distance from a star at which liquid water could exist on orbiting planets' surfaces.

5. It is the amount it takes for Earth to turn on its axis.

6. Interacting parts of the Earth that are dependent and connected with each other.

7. It includes all life forms, even organic matter that has decomposed.

8. It is marked by particular weather patterns and daylight hours, resulting from the earth's changing position with regard to the sun.

9. The planets are smaller blobs captured by the star.

10. It may be an infinity of universes, all with their own laws of physics, their own collections of stars and galaxies (if stars and galaxies can exist in those universes), and maybe even their own intelligent civilizations.
