Planets are formed through a process called accretion, where dust and gas in a planetary disk gradually come together to form larger and larger bodies. Gravitational forces eventually cause these bodies to collide and merge, leading to the formation of planets.
Planets were not "invented" but rather formed naturally as part of the process of stellar evolution. Planets are thought to have originated from a swirling disc of gas and dust surrounding a young star, known as a protoplanetary disc, eventually accreting into planetary bodies.
The terrestrial planets are believed to have formed through a process called accretion, where dust and gas in the protoplanetary disk around the young sun collided and stuck together, gradually building up larger bodies. These bodies continued to grow through further collisions and merging of smaller objects, eventually forming the rocky planets Mercury, Venus, Earth, and Mars.
They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
When a star explodes, many dust particles get pulled together to form stars, planets, and moons. Once the particles start to group, smaller bodies will rotate around bigger bodies. With collisions narrowing down what bodies will last, all the little individual particles are formed into those stars, planets, and moons. Moons are generally formed by particles shot out in space during collisions.
The nebular hypothesis is a widely-accepted theory that explains the formation of the solar system. It suggests that the Sun and planets formed from a spinning disk of gas and dust called a solar nebula. As the nebula contracted due to gravity, it flattened into a disk and the Sun formed at the center, while planets and other celestial bodies formed from material in the disk.
Yes, planets are formed from the same clouds of gas and dust as stars. These clouds are called molecular clouds, and they consist mostly of hydrogen and helium along with other elements. As the cloud collapses under gravity to form a star, leftover material congregates to form planets and other smaller bodies in the newly formed solar system.
The compound formed when iron and chlorine are combined is called iron(III) chloride, also known as ferric chloride.
This process is called accretion. It involves small particles like rocks, gas, and dust clumping together due to gravity and sticking to each other to form larger bodies like planets. Over time, these bodies continue to collide and grow in size until they become fully formed planets.
Compounds are formed when elements of matter are chemically combined.
It is called the cruciform. It is the combined shapes of the nave and transepts.
Planets and other objects in the solar system formed from a rotating disk of gas and dust known as the solar nebula. Gravity caused the particles in the nebula to collide and stick together, gradually forming larger and larger bodies. Eventually, these bodies accreted into planets, moons, asteroids, and other objects in the solar system.
