Lesson 1: Our Solar System What makes up our solar system? When we think of the solar system most of us think of eight planets orbiting around the sun. However‚ the solar system is a lot more complicated‚ larger and exciting than this simple description. The solar system is a gravitationally bound system with all the objects in this system revolving around the sun. The eight planets revolving around the sun are: Mercury‚ Venus‚ Earth‚ Mars‚ Jupitar‚ Saturn‚ Neputune‚ Uranus and Pluto. However‚ the

THE SOLAR SYSTEM T The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it‚ all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system’s mass (well over 99%) is in the Sun. Of the many objects that orbit the Sun‚ most of the mass is contained within eight relatively solitary planets whose orbits are almost circular and lie within a nearly flat disc called the ecliptic

The Origin of the Solar System A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. The disturbance could be‚ for example‚ the shock wave from a nearby supernova. As the cloud collapses‚ it heats up and compresses in the center. It heats enough for the dust to vaporize. The initial collapse is supposed to take less than 100‚000 years. The center compresses enough to become a protostar and the rest of the gas orbits/flows around it

The Solar System The solar system still to this day one of the most fascinating subjects of study in the science world. In our time‚ we are one of the first generations to see the planets of our solar system up close‚ and we have been able to view evolution of these planets through time. Our solar system consists of a middle aged star called the Sun‚ 9 planets‚ about 100 moons‚ thousands of asteroids‚ millions of icy bodies‚ and many comets revolving around all of it. We can begin by looking

Advantages of and Problems with Solar Energy by Ethan Goffman I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that. – Thomas Alva Edison‚ 1931 The oil embargo of the 1970s prompted a national surge of interest in solar energy. A solar water heater was installed in the White House‚ and photovoltaic panels first came into play‚ notably in California. While previously solar power as a direct source of electricity

The Solar System My project is about the Solar System. The Solar System is made up of all the planets that orbits the Sun. The Solar System consists of moon‚ comets‚ asteroids‚ minor planets‚ dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is the more gravity it has. The Sun is the star at the center of the Solar System. After the sun is Mercury‚ the innermost planet in the

Solar System About 4‚700 million years ago‚ the Solar System was just a spinning disc of dust and gas. The dust began to collect together and our Sun formed at the centre. Around Sun‚ lumps of rock joined up to form smaller bodies and‚ like the Sun‚ they heated up. But because they were smaller they soon cooled down and became planets. Sun accounts for 99.85 per cent of mass of the solar system. About 1.3 billion earths would fit inside the sun. The solar system consists of the Sun; the nine planets

1. Our solar system is made up of the sun and everything that travels around it. This includes eight planets and their natural satellites such as Earth’s moon; dwarf planets such as Pluto and Ceres; asteroids; comets and meteoroids 2. The sun is the center of our solar system. It contains almost all of the mass in our solar system and exerts a tremendous gravitational pull on planets and other bodies. 3. Our solar system formed about 4.6 billion years ago. 4.
