The Stars Unit Review Practice
answers
1. Why did the scientist become an astronomer?
Because he couldn't resist the pull of the stars. They were a real "gravity" to him!
2. What is a constellation?
A group of stars that come together for a good old celestial party. They're basically the "celebrities" of the night sky!
3. What is the closest star to Earth?
Well, it's definitely not my neighbor's porch light. But if we're talking about actual stars, it's our friendly neighborhood star, the Sun!
4. How are stars formed?
They start off as little twinkling hopes and dreams in the cosmic nursery. Then, through gravitational attraction and an intense amount of pressure, they ignite into glorious balls of fire!
5. What determines a star's brightness?
Their talent on the celestial dance floor! Just kidding. It actually depends on their size, temperature, and distance from Earth. Some stars are just naturally "hotter" than others.
6. What are the three main types of stars?
There are the "superstars" - the massive ones that shine the brightest and live fast and die young. Then we have the "main sequence" stars - the average Joes of the stellar world. And lastly, we have the "white dwarfs" - the burnt-out remains of once vibrant stars.
7. How do stars die?
Well, they don't have an expiration date like a carton of milk, but they do eventually run out of fuel. Some go out with a bang in a dazzling explosion called a supernova, while others quietly fade away into cosmic dust.
8. What is a black hole?
It's like the supermassive vacuum cleaner of the universe, sucking everything near it into a bottomless pit. It's the ultimate "eating machine" that not even a slice of interstellar pizza can escape from!
9. How are stars different from planets?
Stars are like the powerhouses of the galaxy, generating heat and light through nuclear fusion. Planets, on the other hand, are like the "cool kids" of the cosmic block, just casually orbiting around their star.
10. Can stars collide?
Oh, definitely! But don't worry, it's not like they're playing galactic bumper cars. Instead, when stars collide, it's a mesmerizing display of cosmic fireworks, and sometimes they even merge to create a whole new star. It's like the ultimate stellar love story!
