Answer: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). … Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula.
How did a supernova contribute to the formation of the solar system?
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
How were the planets in the solar system formed ?( 1 point?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Which planet formed first in our solar system?
Jupiter Jupiter was probably the first planet in the solar system to form, new research suggests. Its existence may have influenced how the planets evolved into the order we see today.
Which term best describes how the solar system formed?
Explanation: Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula.
How are supernovae connected to Earth’s formation?
Heavier elements were formed in the cores of stars found in the early universe and through their explosions as supernovae. It took many billions of years of star formation and supernovae to produce a sufficient amount of heavy elements to begin to form solar systems that included rocky planets similar to Earth.
Do supernovae create solar systems?
Summary: According to one longstanding theory, our Solar System's formation was triggered by a shock wave from an exploding supernova. It injected material from the exploding star into a neighboring cloud of dust and gas, causing it to collapse in on itself and form the Sun and its surrounding planets.
How are planets formed step by step?
According to our current knowledge, planets are formed around a new star by condensing in a disc of molecular gas and dust, embedded within a larger molecular cloud. Condensation increases until they become giant planets, which are heated, then cleanse their orbits in the disc and possibly bend it.
What order were the planets formed?
The giant planets were the first to form, taking a few million years. The terrestrial planets formed more slowly from coliisions between planetesimals, and took up to 100 million years. Earth and Venus were the last to form because they are more massive. Mars growth was halt early by Jupiter.
How old is the world?
4.543 billion yearsEarth / Age Today, we know from radiometric dating that Earth is about 4.5 billion years old. Had naturalists in the 1700s and 1800s known Earth's true age, early ideas about evolution might have been taken more seriously.
