It is called a 'proto-planet', this is the 'before-planet'-stage; It has gathered enough mass to form a large gravity field and cause a spherical shape.
Rain is believed to have first fallen on Earth around 2.4 billion years ago during the early stages of the planet's formation.
Rain first appeared on Earth approximately 2.4 billion years ago during the early stages of the planet's formation.
An organism in the early stages of its development is an embryo.
Protoplanets or planet embryos.
They are called "piglets".
Forsterite is a magnesium silicate mineral commonly found in meteorites. It is a type of olivine mineral that forms in the early stages of planet formation. Forsterite is also known as Mg-rich olivine.
When the sperm and egg of two animals meet, they create a zygote. It is then called an embryo during the early stages of development and later called a foetus.
The most widely accepted theory for the formation of the Moon is the Giant Impact Hypothesis. According to this theory, a Mars-sized object collided with the early Earth, causing debris to be ejected into space. This debris eventually coalesced to form the Moon. The stages include the impact event itself, the formation of a debris disk around the Earth, and the accretion of this material to form the Moon.
The main difference between the nebular and condensation theories is their emphasis on different aspects of planet formation. Nebular theory focuses on the collapse of a rotating nebula to form a star and planets, while condensation theory emphasizes the role of solid particles (dust and gas) in the early stages of planet formation.
Early Earth likely lost most of its hydrogen and helium because they are lightweight gases that could escape the planet's gravity due to their high kinetic energy. This loss likely occurred during the early stages of Earth's formation when the planet was still molten and experiencing intense heat.

Giant planets can migrate due to interactions with the gas disk in the early stages of a planetary system's formation. This migration process is called planet migration and is influenced by gravitational forces between the planet and gas in the disk. Additionally, interactions between multiple planets in a system can also lead to migration as they exchange angular momentum.
