Planets formed by _____________because particles in space stuck together
Planets formed by accretion because particles in space stuck together.
Planets formed by a process called accretion, where particles in space stuck together. Accretion is the gradual accumulation and collision of small particles called planetesimals and dust grains in a protoplanetary disk. These disks are formed from the leftover material after the birth of a star, known as a solar nebula.
To understand this process better, scientists study different aspects of planet formation, such as astrophysics, planetary science, and cosmology. The most common way to explore this topic is through computer simulations based on known physical laws and observations. These simulations emulate the formation and evolution of planetary systems.
Scientists also analyze data from astronomical observations and spacecraft missions. These observations provide valuable clues about the conditions and processes that led to the formation of planets in our own solar system and beyond. By studying the composition, structure, and movement of celestial objects, scientists can infer the mechanisms that were involved in planet formation.
Overall, understanding the process of planet formation involves a multidisciplinary approach that combines theoretical modeling, observations, and experimental data.
