19: The Origin of the Universe and Our Solar System

The universe began 13.77 billion years ago when energy, matter, and space expanded from a single point. Evidence for the big bang is the cosmic "afterglow" from when the universe was still very dense, and red-shifted light from distant galaxies, which tell us the universe is still expanding.. The big bang produced hydrogen, helium, and lithium, but heavier elements

All the foregoing constraints are consistent with the general idea, introduced in Other Worlds: An Introduction to the Solar System, that the solar system formed 4.5 billion years ago out of a rotating cloud of vapor and dust—which we call the solar nebula —with an initial composition similar to that of the Sun today. As the solar nebula collapsed under its

Other Objects in the Solar System | Earth Science

The dwarf planets of our solar system are exciting proof of how much we are learning about our solar system. With the discovery of many new objects in our solar system, in 2006, astronomers refined the definition of a planet. Their subsequent reclassification of Pluto to the new category dwarf planet stirred up a great deal of controversy.

2.2: Origin of the Solar System

Our solar system formed as the same time as our Sun as described in the nebular hypothesis. The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets. The spinning nebula collected the

Solar system | Definition, Planets, Diagram, Videos, & Facts

5 days ago· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

What Formed Last in the Solar System? (The Last Planet Formed)

The last planet to form in our solar system was Neptune. It is thought to have formed about 4.5 billion years ago, soon after the formation of the sun. Which Objects Formed Last in Our Solar System Brainly? The objects that formed last in our solar system are the planets. The planets were formed from the leftover gas and dust that was not

7.4: Origin of the Solar System

These disks resemble our own solar system''s initial stages of formation billions of years ago (Figure (PageIndex{2})). Figure (PageIndex{2}) Atlas of Planetary Nurseries. These Hubble Space Telescope photos show sections of the Orion Nebula, a relatively close-by region where stars are currently forming.

6 FAQs about [Which object s formed last in our solar system]

Which objects formed last in our Solar System?

In our solar system, the objects that formed last were the planetesimals, including asteroids, comets, and smaller celestial bodies. These planetesimals resulted from the residual dust and gas left after the formation of the sun and planets. Our solar system began its formation about 4.6 billion years ago from a giant molecular cloud.

How did the Solar System come into existence?

The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, resulting in a solar nebula, a swirling disc of material that collided to form the solar system. The solar system is located in the Milky Way's Orion star cluster.

How long did the solar wind last?

After between three and ten million years, [ 38 ] the young Sun's solar wind would have cleared away all the gas and dust in the protoplanetary disc, blowing it into interstellar space, thus ending the growth of the planets. [ 49 ][ 50 ]

What type of star orbits the Sun?

Astronomers classify it as a G-type main-sequence star. The largest objects that orbit the Sun are the eight planets. In order from the Sun, they are four terrestrial planets (Mercury, Venus, Earth and Mars); two gas giants (Jupiter and Saturn); and two ice giants (Uranus and Neptune). All terrestrial planets have solid surfaces.

Do all stars have planetary systems?

Only 15% of stars in the galaxy host planetary systems, and one of those stars is our own sun. Revolving around the sun are eight planets. The planets are divided into two categories based on their composition, terrestrial and Jovian. Terrestrial planets, including Mercury, Venus, Earth, and Mars are primarily made of rocky material.

Why do solid objects in the outer Solar System contain more volatiles?

Due to their greater distance from the Sun, the solid objects in the outer Solar System contain a higher proportion of volatiles, such as water, ammonia, and methane than those of the inner Solar System because the lower temperatures allow these compounds to remain solid, without significant rates of sublimation.
