In Earth science, a shapeless cloud of gas and dust is typically referred to as a "nebula." These nebulae are often the birthplaces of stars and planetary systems, as they contain the necessary materials for star formation. Over time, gravity can cause parts of the nebula to collapse and condense, leading to the formation of new celestial bodies.
A shapeless cloud of gas and dust in space is often referred to as a nebula. These clouds are primarily composed of hydrogen, helium, and other ionized gases, along with dust particles. Nebulae can serve as the birthplace of stars, as gravitational forces can cause regions within them to collapse and form new celestial bodies. They also play a role in the recycling of materials in the universe, contributing to the formation of new stars and planets.
The Earth has no rings. There may be a VERY tenuous dust cloud, but that mass would mostly have been skimmed off by the Moon's gravity, causing it to either fall to Earth or ejecting it from near-Earth space. So if there is a dust cloud near the Earth, it is too thin to detect.
Before the Earth, the solar system was a swirling disk of gas and dust. This material eventually clumped together to form the planets, including Earth. Scientists believe that the Earth began to form about 4.5 billion years ago.
The Earth formed about 4.5 billion years ago from a cloud of dust and gas in space, a remnant of the solar system's formation from a nebula. Gravity caused the cloud to collapse, forming the Sun at the center and the planets, including Earth, from the remaining material in orbit around it.
The solar dust cloud that formed Earth originated from the solar nebula, a rotating disk of gas and dust left over from the formation of the Sun about 4.6 billion years ago. As gravity caused the particles in the nebula to clump together, they formed larger bodies, eventually leading to the creation of protoplanets. Over time, these protoplanets collided and merged, accumulating mass and leading to the formation of Earth. The process involved complex interactions of gravity, heat, and chemical reactions, resulting in the diverse materials that make up our planet today.

a dust cloud
The dust cloud theory, which suggests that the solar system formed from a rotating disk of gas and dust, was proposed by Russian astrophysicist Viktor Safronov in the 1960s. He published his ideas in his book "Evolution of the Protoplanetary Cloud and Formation of the Earth and Planets."

A Cloud of Red Dust was created on 1997-10-06.
The dust-cloud theory proposed that Earth's Moon formed from debris ejected into space when a Mars-sized object collided with Earth early in its history. The debris formed a disk around Earth which eventually coalesced to form the Moon. This theory is supported by evidence such as the similar isotopic composition of Earth and Moon rocks.
dust
A cloud of dust and gas in space is known as a Nebula.
A cloud of grain dust
The presence of dust in the air can expedite cloud formation by providing a surface for water droplets to condense and form cloud droplets around. Dust particles act as cloud condensation nuclei, which help water vapor in the air to condense into clouds.
