- The text does not specify the exact ratio
- 10 times
- 100 times (correct)
- 400 times
Why does the moon and sun appear to be the same size in the sky from Earth's perspective?
Why does the moon and sun appear to be the same size in the sky from Earth's perspective?
- The moon is 400 times smaller than the sun but also 400 times closer to Earth. (correct)
- The sun's light refracts around the moon, creating an optical illusion.
- The moon is the same size as the sun but appears smaller due to its distance.
- The moon's orbit is tilted at the perfect angle to make it appear the same size.
What happens during a total solar eclipse?
What happens during a total solar eclipse?
- The Earth moves between the moon and the sun, casting a shadow on the moon.
- The sun's light refracts around the moon, creating a ring of light.
- The moon moves between the Earth and the sun, completely blocking the sun's light. (correct)
- The moon reflects sunlight onto a specific area of the Earth's surface.

Study Notes
The Sun and Solar Eclipses
- The sun is enormous, 10 times larger than any other object in the solar system and 100 times larger than Earth.
- The moon is 400 times smaller than the sun, but is also 400 times closer to Earth, making it appear the same size in the sky.
Lunar Coincidence and Solar Eclipses
- Due to the moon's size and distance, it can cross in front of the sun and block its light, causing a solar eclipse.
- This coincidence occurs because the moon's orbit is tilted a few degrees from Earth's orbital plane.
- Eclipses only happen when the moon's tilted orbit aligns with Earth's orbital plane.
Frequency of Solar Eclipses
- Between 2 and 5 solar eclipses occur on Earth each year, but a specific location only gets a total eclipse every few hundred years.
- It's a rare opportunity to witness a total solar eclipse.
Preparing for a Solar Eclipse
- To see a total solar eclipse, you need to be in the path of totality, a small stripe on Earth where the moon's shadow completely covers the sun.
- You can use maps and apps to find a good viewing spot, but weather conditions are not guaranteed.
- Plan ahead to know exactly when totality will occur at your location.
Maximizing the Eclipse Experience
- Consider using an app like the solar eclipse timer, which provides precise timings for every key moment of the eclipse.
- With proper planning, you can make the most of this rare cosmic event.
