Did you know about our Sun?

oooo

We have all seen at least one star in the daytime!

We have all seen at least one star in the daytime!

  • Our Sun is a 4.5 billion years old dwarf star.
  • A hot glowing ball of both gases ~ hydrogen and helium.
  • It’s our solar system’s only one star.
  • If the sun would go out, no life could survive on most of earth’s surface within a few weeks ~ water and air would freeze over into sheets of ice.

Here’s the Sun, Earth and Moon to scale

Here’s the Sun, Earth and Moon to scale

  • Our sun is the largest object in our solar system.
  • Its diameter is around 865,000 miles.
  • Its gravity holds our solar system together, keeping everything from the planets, comets, asteroids to the smallest bits of debris in orbit around our Sun.

How many Earths could fit across the Sun?

How many Earths could fit across the Sun?

  • To put that in perspective, if Earth were the size of a marble, the Sun would be a giant beach ball.

How many Earths could fit the height of Solar Flares?

How many Earths could fit the height of solar flares?

  • Solar flares are giant explosions on the sun that send energy, light and high speed particles into space.from the release of magnetic energy associated with sunspots.
  • Flares are our solar system’s largest explosive events.
  • They are seen as bright areas on the sun and they can last from minutes to hours.

oooo

What’s the Sunspots?

What are the Sunspots?

  • Sunspots typically stretch 1,000 to 100,000 miles across.
  • Sunspots are dark areas that appear on the surface of the Sun.
  • They are caused by strong magnetic activity within the Sun.
  • Sunspots are not permanent and they can move slowly across the surface of Sun changing size as they move.

oooo

or car take to get to the Sun?

How long does aeroplane or car take to get to the Sun?

  • On an average jet plane, flying at 550 miles per hour, it would take 19.29 years,
    or 7,045 days to travel the 93 million miles to the Sun.

oooo

How many Earths can fit in the distance from the Sun to Earth?

How many Earths can fit in the distance from the Sun to Earth?

  • Nearly 12,000 Earths could fit in the distance from the Sun to Earth, assuming they were lined up end-to-end.
  • The Earth’s diameter is roughly 8,000 miles, while the distance from Earth to the Sun is about 93 million miles

What is a Solar Eclipse?

What is a Solar Eclipse?

  • The solar eclipse occurs when the Moon is positioned precisely
    between the Earth and Sun.

Solar Eclipse – Perfect fit!

Solar Eclipse – Perfect fit!

  • The reason a total solar eclipse appears as a perfect fit is because the Moon is about 400 times smaller than the Sun, but it is also about 400 times closer to Earth.
  • This proportional relationship means that, from our perspective on Earth, the Moon can completely cover the Sun’s disk during a total eclipse, creating a breath-taking celestial event.

oooo

What is a shadow path in a solar eclipse?

What is a shadow path in a Solar Eclipse?

  • The Moon blocks all of the Sun’s light.
  • This is called a total solar eclipse.
  • As the Moon blocks the Sun’s light, it casts a shadow on part of the Earth.
  • The Moon’s shadow creates a trail as Earth rotates.
  • This trail is called the path of totality.
