All of us at one time or other believed we were the center of the Universe...uhmmmm, some people still have big enough egos's that they believe they ARE the center of the Universe.... In our Solar System, the Sun is the center of all we hold dear. Without the Sun we would be nothing but a chunk of matter floating in space. Our Sun—the heart of our solar system—is a yellow dwarf star, a hot ball of glowing gases. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit. (Largest mass=largest force of gravity). How did the Sun get the honor of being in the center of our Solar System? Well, the answer should be pretty obvious.....it's HUGE! It's the most massive ball of burning plasma nearest to us. One story is that the Sun formed and became a large ball of sucking gravity that tried to pull every piece of matter into it that it could. As it began to swallow hydrogen (the most plentiful gas in space), it began to heat up and fuse making helium. This just made the Sun hotter and larger. Since matter was pulling in from all over space the faster the objects sped by, their distance and mass countered the Sun's massive pull of gravity. Imagine a rotating cloud of gas surrounding the Sun, the gases near the Sun are spinning faster than the gases further away. (Remember how we spun on the spinning plate, held weights out then pulled them in?) The same motion occurred in the massive cloud of gas that was spinning, flattening and coming together in the form of rocky planets and cooler gas spheres. Mass and distance were key elements of the formation of our Solar System. Scientists are looking at young solar systems through our modern telescopes and observing similar patterns of matter coming together around newly forming stars. Five percent of these star observations show similar sized "Jupiter-like" planets. When we study the Solar System we need to remember forces like gravity, inertia and centrifugal forces. They help us get a tiny understanding of how our Solar System may have formed.

The guy on the phone looked like he was really mad.

It's crazy that the sun is the center of the universe. It makes sense though because every planet is revolving around the sun.

When we did the spinning plate thing, I got kind of dizzy.

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
