What are protoplanetary objects?

Answer 1

Protoplanetary objects are are clumps of material which will ultimately form a planet.

A protoplanetary disc forms when enough solid material orbits a newly formed star. The material in the disc begins to clump together into larger and larger clumps. These are protoplanetary objects or bodies. Eventually, all of the protoplanetary bodies in a particular orbit will combine to form a planet. This process can take millions of years. Stars are born in clouds of dust and gas. The star consumes almost all of the material.

Protoplanetary objects are celestial bodies that are in the early phases of forming a planetary system; they can be thought of as protoplanetary disks or protoplanets. These objects are made up of gas, dust, and other materials that are bound together by gravity; eventually, these materials will form planets, moons, asteroids, and other bodies in the solar system.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
