🌞The sun appears to be about the same size as a pea held at arm's length.
🌍The Earth is approximately 70 cm away from the pea-sized sun in this scale model.
🔭Alpha Centauri, the nearest sun-like star, is represented by a slightly larger pea and is visible from Earth.
🚀Proxima B, the nearest known exoplanet to our solar system, is located about 3.5 cm from Proxima Centauri.
🌌The video emphasizes the vast distances in space and the challenges of space travel.
Why is a pea used to represent the sun in the scale model?
—A pea is used because it appears to be about the same size as the sun when held at arm's length.
Can we see Alpha Centauri from Earth?
—Yes, Alpha Centauri is one of the brightest stars in the sky and is visible from Earth.
How far away is Proxima B from Proxima Centauri?
—Proxima B is located about 3.5 cm away from Proxima Centauri in this scale model.
What are the challenges of space travel to the nearest stars?
—The vast distances in space pose significant challenges for space travel, including the time required and the technological limitations.
How big is the solar system compared to the rest of the universe?
—The solar system is small compared to the vastness of the universe, which contains billions of galaxies.
