For example, Earth''s large moon is probably the result of a collision between Earth and another small planet early in solar system history. That would help explain why

Hubble solar-system observations have several bizarre cases of asteroids disintegrating before our eyes. Some are the victim of collisions; others slowly spin up until they slough off material.
18.1: Introduction to the Solar System
Today, we know that our solar system is just one tiny part of the universe as a whole. Neither Earth nor the Sun are at the center of the universe. However, the heliocentric model accurately describes the solar system. In our modern view of the solar system, the Sun is at the center, with the planets moving in elliptical orbits around the Sun.

6 FAQs about [What does the solar observation system include ]
What is solar observation?
Solar observation is the scientific endeavor of studying the Sun and its behavior and relation to the Earth and the remainder of the Solar System. Deliberate solar observation began thousands of years ago. That initial era of direct observation gave way to telescopes in the 1600s followed by satellites in the twentieth century.
How did telescopic observations contribute to the discovery of planets?
Telescopic observations resulted in the discovery of moons and rings around planets, and new planets, comets and the asteroids; the recognition of planets as other worlds, of Earth as another planet, and stars as other suns; the identification of the Solar System as an entity in itself, and the determination of the distances to some nearby stars.
How many stars are in the Solar System?
Our Solar System contains the Sun and everything that orbits it. containing billions of stars. The Sun is one of these stars. The Sun is the largest object in the Solar System. The Sun’s huge gravitational field keeps many other objects - planets, dwarf planets, asteroids and comets - in orbit around it.
How many planets are in the Solar System?
Our Solar System contains the Sun, 8 planets, and lots of smaller objects. It formed 4,500 million years ago. It is on an outer spiral arm of the Milky Way galaxy. The 4 planets closest to the Sun are the inner or terrestrial planets. They are small, warm, rocky worlds with few (or no) moons and no rings. They are: Mercury, Venus, Earth, and Mars.
What is a planetary system called?
The Solar System is one of many planetary systems in the galaxy. The planetary system that contains Earth is named the "Solar" System. The word "solar" is derived from the Latin word for Sun, Sol (genitive Solis). Anything related to the Sun is called "solar": for example, stellar wind from the Sun is called solar wind.
What can a solar observer learn from NASA?
Solar observers may discover that solar physics and astronomy is completely fascinating, and that the sun is a very exciting variable star! The NASA website (see the Resources section) is one of many good sources of further information about solar rotation and other factors that may affect the solar observer.
