Solar System

The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its

Science 101: The Solar System

All four Jovian planets have multiple moons, sport ring systems, have no solid surface and are immense. The largest Jovian is also the largest planet in the solar system, Jupiter. Nearby is Saturn, the solar system''s second largest planet. Its signature rings are wide enough to fit between Earth and the moon, but are barely a kilometer thick.

Planet

The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets). A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

Solar System Facts

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.

What are the 9 Planets of the Solar System?

The sun is the largest object in the solar system. In fact, it accounts for 99% of the solar systems'' mass. Astronomers estimate that the solar system is more than 4.5 billion years old. Here is a rundown on the 9 planets of the solar system:

Solar System Facts | Information, Size, History and Definition

The planets of the outer solar system are Jupiter, Saturn, Uranus, and Neptune (Pluto is now classified as a dwarf planet): The first thing to notice is that the solar system is mostly empty space. The planets are very small compared to the space between them. Even the dots on the diagrams above are too big to be in proper scale with respect to

Moons of Our Solar System

How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth''s Moon. Since it was named before we learned about other planetary satellites, it is called simply "Moon." According to the NASA/JPL Solar System Dynamics team, the current tally []

What Is the Solar System?

Solar System Formation. The solar system is located in one of the spiral arms of the Milky Way galaxy. It was born about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed. Most of the material was pulled toward a central point: nearly all of the solar system''s mass—99.8%—is in the Sun.

Our Solar System

Our solar system features eight planets, seen in this artist''s diagram. Although there is some debate within the science community as to whether Pluto should be classified as a Planet or a dwarf planet, the International Astronomical Union has decided on the term plutoid as a name for dwarf planets like Pluto.

Planets in Order From the Sun in the Solar System

Mercury is the first planet from the Sun in our Solar System.He amazed people with his retrograde movements from the beginning and his recently discovered phases and moon-like similarities. Mercury is the closest (first) planet to the Sun and the smallest member of our Solar System s diameter is 4,878 kilometers, and its mass is only 5.5% of the mass of the Earth.

The Solar System: Planets and Formation Explained

The large mass of the sun produces an enormous gravitational pull that keeps all the planets of the solar system in their orbits. Even dwarf planet Pluto (formerly the ninth planet outright), which is six billion kilometers (3,728,227,153 miles) away, is kept in orbit by the sun.
