The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine . If you insist on including Pluto, it would come after Neptune on the list.
What are the 4 main stages of a solar system?
Scientists believe that terrestrial planets, like Earth, formed by clumping together from dust and gas into into hot blobs of molten metal and rock several billion years ago. After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution .
What is the pattern of the solar system?
When we look at our solar system in the “modern” sense as defined by Copernicus and Kepler, we immediately see several interesting patterns: The inner four planets, Mercury, Venus, Earth and Mars, are all small and rocky . The next four planets, Jupiter, Saturn, Uranus and Neptune, are all gas giants.
Which is the first step in building a solar system?
The correct answer is: An explosion disturbs the gas and dust in the nebula . Solar systems begin to form when an explosion disturbs the gas and dust in the nebula. The explosion could be from a supernova.
How was the solar system formed step by step?
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.
What is each planet made of?
Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock , containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.
How is our solar system different from others?
Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That’s just how many we’ve found so far.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
How many steps are there in the formation of a solar system?
6 steps to how the solar system was formed.
What planets exist in our solar system?
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune ; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
How old is our solar system?
Age and Origin of the Solar System. The age of the solar system, derived from the study of meteorites (thought to be the oldest accessible material around) is near 5 billion years; that of the Earth is taken as 4.6 billion years .
Is the earth a ball of gas?
It’s smaller than the four gas giants — Jupiter, Saturn, Uranus and Neptune — but larger than the three other rocky planets, Mercury, Mars and Venus. Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is mostly round because gravity generally pulls matter into a ball . ... Related: How big is Earth?
What is the formation of the universe?
Our universe began with an explosion of space itself – the Big Bang . Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
What is the solar system for kids?
The solar system consists of the Sun and everything that orbits, or travels around, the Sun. This includes the eight planets and their moons, dwarf planets, and countless asteroids, comets, and other small, icy objects. However, even with all these things, most of the solar system is empty space.
Which is the only planet that can sustain life?
Nonetheless, Earth is the only place in the Universe known to harbor life.
