What does A cloud fragment too small to collapse into a main sequence star becomes a?
A brown dwarf stellar object (13.5 - 80 Jovian masses) or a lone "planet".
A planet technically is defined as "an object that orbits a star and is able to become a sphere by gravity and has cleared it orbital neighbourhood of other objects" but I do not know of a term that describes a planet size object that does not orbit a star.

What did our sun look like before it was a star?
The Sun (and all the planets) started their lives in a giant cloud of cold molecular gas and dust. And then about 4.6 billion years ago, something bumped into the cloud, like the gravity from a passing star, or shockwaves from a supernova, causing the cloud to collapse. With the collapse, the mutual gravity from the particles in the cloud pulled together, and formed pockets of denser material in the cloud. These were star forming regions, and one of them was to become the Solar System.
What sequence best describes the formation and elevation of stars with masses similair to the sun?
Stars with masses similar to the sun form in giant molecular clouds through gravitational collapse of dense regions. As the star-forming cloud contracts, it heats up and a protostar forms at the center. Eventually, nuclear fusion ignites in the core, leading to a stable star like our sun.
What are the basics steps of star formation?
Star formation begins with the gravitational collapse of a dense region within a molecular cloud. As the cloud collapses, it heats up and forms a protostar. The protostar continues to accumulate mass and eventually ignites nuclear fusion in its core, becoming a main-sequence star.
When the tip of the funnel cloud touches the ground it becomes a?
tornado clouds
What begins the process of the solar system?
The answer to this question depends on your school of thought.If you side with science, the answer is the Big Bang.If you side with religion, the answer is God.
Cloud of dust that becomes a star?
A cloud of dust that becomes a star forms through the process of gravitational collapse. As the dust particles come together, they begin to heat up and eventually ignite nuclear fusion, which results in the birth of a new star.
When a cloud fragment has compressed enough so that it glows?
When a cloud fragment compresses enough to glow, it indicates that the pressure and temperature within the fragment have reached a critical point where nuclear fusion reactions can start in its core. This marks the beginning of a star's formation, as gravitational forces continue to compact the cloud and nuclear reactions sustain the star's energy production.
What makes an interstellar cloud collapse?
Gravity.
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million k becomes what?
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million K becomes a protostar. As gravity causes the gas to contract and heat up, nuclear fusion reactions ignite in its core, marking the birth of a star. The protostar will continue to evolve as it balances the inward pull of gravity with the outward pressure from nuclear fusion.
How does the Jeans mass determine the formation of a star when a sound wave travels through a gas cloud?
The Jeans mass is the minimum amount of mass needed for a gas cloud to collapse and form a star. When a sound wave travels through a gas cloud, it can cause the cloud to become unstable and collapse if its mass exceeds the Jeans mass. This collapse leads to the formation of a star.
What role does gravitational collapse play in the process of star formation?
Gravitational collapse is a crucial step in the process of star formation. When a cloud of gas and dust in space collapses under its own gravity, it becomes denser and hotter, eventually leading to the formation of a protostar. This gravitational collapse is what initiates the fusion reactions in the core of the protostar, eventually leading to the birth of a new star.
Does rain form when water evaporates?
Well first it turns into a cloud the when the cloud becomes to heavy the water falls and becomes rain
What is a star thought to be born?
A star is thought to be born in a molecular cloud, a dense region of gas and dust in space. Under the influence of gravity, these materials collapse and clump together, leading to increased temperature and pressure at the core. When the core temperature becomes high enough, nuclear fusion begins, converting hydrogen into helium and releasing energy, which marks the birth of a new star. This process is often depicted in a sequence known as stellar formation, transitioning from a protostar to a main-sequence star.
What is a star is a baby what is it called?
A star is often referred to as a "protostar" during its early formation stage. This occurs when gas and dust in a molecular cloud collapse under gravity, leading to the accumulation of material that heats up and begins to form a new star. As the protostar continues to gather mass and temperature rises, it eventually reaches the point of nuclear fusion, at which point it becomes a main-sequence star.
Which process is required to allow a gravitationally-collapsing gas cloud to continue to collapse?
The process required to allow a gravitationally-collapsing gas cloud to continue collapsing is radiative cooling. Radiative cooling removes thermal energy from the gas cloud, facilitating further collapse under the influence of gravity.
How does the conservation of angular momentum slow down a cloud's collapse?
The conservation of angular momentum slows down a cloud's collapse by causing it to spin faster as it shrinks in size. This increased spin creates a centrifugal force that counteracts the force of gravity, helping to stabilize the cloud and prevent it from collapsing too quickly.
HOW DID DUST cloud form in World Trade Center?
it collapse after two planes hit it
