Gravity.
Gravity is the force that pulls dust and gas together in space. The gravitational attraction between particles causes them to clump together, eventually forming larger structures like stars and planets.
Ice clouds in interstellar space play a crucial role in the formation of new stars and planets by providing the raw materials needed for the process. These ice clouds contain elements and molecules that can clump together under the force of gravity, eventually forming dense cores that collapse and give rise to new stars and planetary systems.
If Jupiter were to collide with the Sun, it would result in a catastrophic event with massive explosions and the destruction of both planets. The impact would release an immense amount of energy, causing widespread devastation in the solar system.
The gravitational force is the greatest force in the universe. It is responsible for holding together galaxies, stars, planets, and all celestial bodies.
Gravity is the force that causes objects in space to be held together. It is a fundamental force of nature that governs the motion of celestial bodies, keeping planets in orbit around stars, and holding galaxies together.
Planet formation occurs through the process of accretion, where dust and gas in a protoplanetary disk clump together to form planetesimals, and eventually planets. Gravity plays a crucial role in this process, pulling material together to form larger and larger bodies. Over time, these planetesimals collide and merge, forming planets.
Dust clouds in space can gradually clump together due to gravitational attraction between particles, forming planetesimals. These planetesimals then collide and merge to form larger bodies, eventually accumulating enough mass to become planets. This process, known as accretion, is a key step in the formation of individual planets from dust clouds.
Planetesimal formation.
Planets are formed from a disk of gas and dust surrounding a young star known as a protoplanetary disk. Over time, the particles within the disk collide and stick together, gradually forming larger and larger objects. Eventually, these objects grow into planetesimals, which further accrete material to become planets.
Protoplanets are larger bodies in the process of forming into planets, usually by accreting material from a protoplanetary disk. Planetesimals are small celestial bodies that are precursors to planets, often ranging in size from meters to hundreds of kilometers and are believed to be building blocks for planets. Essentially, protoplanets are further along in the planet formation process compared to planetesimals.
Dust and gas particles in a protoplanetary disk collided and stuck together to form planetesimals, which then collided and accreted to form planets. The process of gravitational attraction and collisions led to the formation of larger bodies within the disk, eventually forming planets.
The stages of the Nebular theory are: 1. Nebula formation - a giant molecular cloud collapses under its own gravity. 2. Disk formation - the nebula flattens into a spinning disk due to conservation of angular momentum. 3. Planetesimal formation - small particles in the disk collide and stick together to form planetesimals. 4. Planet formation - these planetesimals continue to collide and merge to form planets.
Planetesimals are small solid objects that form in the protoplanetary disk around a young star, while protoplanets are larger bodies that develop from the accumulation and collision of planetesimals. Planetesimals are the building blocks that come together to form protoplanets, and eventually, planets. So, planetesimals are like the "seeds" that grow into protoplanets.
Planetesimals.
Planets form from a disk of gas and dust around a young star. As particles collide and stick together, they grow into planetesimals and eventually planets through a process called accretion. Larger bodies can then attract more material through gravity, continuing to grow in size.
Scientists believe that the solar system is about 4.5 billion years old, and that it began as a cloud of interstellar gas and dust. This cloud of matter then condensed and fragmented into tiny ( compared to planets ) objects called planetesimals. These planetesimals then came together due to gravity to from the planets we know now. It is thought that many asteroids are planetesimals that never came together.
Planets in the solar system are thought to have formed from a giant rotating disk of gas and dust around the young Sun, known as the solar nebula. Small particles in this disk collided and stuck together, gradually growing into planetesimals and eventually forming protoplanets and then fully-fledged planets through accretion and gravitational interactions.
