What's the largest object in the asteroid belt?
Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter, and it's the only dwarf planet located in the inner solar system.
How many high tides occur in a 24 hour period?
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
Two high

Why is a lunar eclipse visible from about half the Earth, while solar eclipse is only visible to a very small region?
Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.
How is a meteor shower created?
Meteor showers are created when Earth passes through the debris left behind by comets or asteroids. This debris is made up of rocks and ice that are ejected from the comet as it orbits the sun.
