What else can I help you with?
What caused dust and condensing material to accrete into planetesimals?
Gravity probably had some effect, but "van der Waals" forces are thought to have been the main cause, in the early stages. These are electrical forces between atoms, molecules, etc.
What does planetismals mean?
Planetesimals are small celestial bodies that formed from dust and gas in the early solar system. They are thought to be building blocks for planets and other larger bodies in our solar system. Planetesimals can range in size from a few meters to hundreds of kilometers in diameter.
What caused the galaxies and planets to form?
Galaxies and planets are thought to have formed from the gravitational collapse of vast clouds of gas and dust in space. Within these clouds, gravity caused the material to clump together, eventually leading to the formation of galaxies composed of billions of stars and planets within these galaxies.
Are jovian planets thought to contain much less rocky material than the terrestrial planets?
Yes, Jovian planets are thought to contain much less rocky material compared to terrestrial planets. Jovian planets are primarily composed of gases like hydrogen and helium, with a small rocky core at their centers. Terrestrial planets, on the other hand, are predominantly made of silicate rocks and metals.
What three types of materials thought to make up the inner planets?
There isn't a specific substance that planets are made of. Most planets are made of solids and/or gases. As far as we know, there may be a planet somewhere out there that's made of liquids.Gases, rocks, and ices
How do planets get their moons?
Moons are thought to form from the same material as planets through a process called accretion, where smaller objects like asteroids or planetesimals are pulled together by the planet's gravity. In some cases, moons may also be captured by a planet's gravity from passing objects in the solar system.
What is the term used to describe an object that is much smaller than a planet and which condensed from a cloud of interstellar gas and dust?
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.
What is Jupiter thought to be like beneath its cloud?
There is thought to be a molecular hydrogen layer, and a liquid metallic hydrogen layer. At high pressures, hydrogen forms a liquid metal which is a very good electrical conductor. We think this because combined with rapid rotation, a dynamo is formed, producing Jupiter's intense magnetic field. There is also thought to be a rocky core that was formed by planetesimals, which basically supplied the initial gravity to hold the gases and create a gigantic gaseous planet.

How are tides planets and black holes related?
There is a force that unites the tides, planets and black holes. Tides are generally thought of as the rise and fall of the level of the oceans due to the gravitational effects of the moon and the sun. Planets have gravity proportional to their masses, and black holes are points of massive gravity. Gravity or its effects unite the three things listed.
why was gravity made or like thought of?
it holds the planets that orbit around the sun and what keeps the moon in orbit around the Earth
What are Planetesimal?
one of the numerous small, solid bodies that, when gathered together, form a planet.
How was your planet thought to have been formed?
Earth, like all planets, was formed by clumps of matter joining together due to gravity.
What caused the galaxies and planets to form?
Galaxies and planets are thought to have formed from the gravitational collapse of vast clouds of gas and dust in space. Within these clouds, gravity caused the material to clump together, eventually leading to the formation of galaxies composed of billions of stars and planets within these galaxies.
The outer planets are made up of which gases?
The composition of Jupiter and Saturn are mostly helium and hydrogen with trace amounts of hydrogen compounds such as methane, ammonia and water. Neptune and Uranus consist mostly of methane, ammonia and water, with small amounts of elemental hydrogen and helium. Jupiter is thought to have no definite core, while Saturn is thought to have a dense core of iron, nickel, silicon and oxygen compounds. Neptune is thought to have a core of molten rock (as well as water, hydrogen, helium, ammonia, and methane). Uranus is thought to have a core similar to Saturn's.
How are the planets in the solar system formed as?
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.
