News

We are off to space! Take your mind on a mission of discovery through our solar system, to the furthest reaches of the Milky Way with these out of this world facts about space for kids!

Nearly everyone has a fascination with amazing space facts, after all, it’s human nature to want to explore. In this infographic we’ve collected over 100 facts about space – So share this with your friends, kids or students to inspire them! They could be the next Neil Armstrong, Michael Fincke or Steve Swanson and join other inspirational NASA astronauts and scientists that carved their marks in the vast ocean of space.

In fact, Australian kids have a rare opportunity to actually meet and learn from NASA staff without travelling to the USA. Thanks to our special program, Mission Discovery, Australian students have a chance to do something extraordinary and literally launch their ideas into space!

And as a teaser, here’s our space facts infographic that smart kids would surely love.

“MISSION OUTER SPACE: SPACE FACTS FOR SMART KIDS!” Infographic Transcription

We are off to space! Take your mind on a mission of discovery through our solar system, to the furthest reaches of the Milky Way with these out of this world facts about space!


The moon is farther away than you think.
When the moon is at farthest point of orbit from earth, you could fit all of the planets in our solar system in the distance between Earth and the Moon.
Distance: 384,400 Km

Diameter
Earth = 12,742 Km
Mercury = 4,879 Km
Venus = 12,104 Km
Mars = 6,771 Km
Jupiter = 139,822 Km
Saturn = 116,464 Km
Uranus = 50,724 Km
Neptune = 49,244 Km
Our moon = 3,474 Km


Just how big is the Sun?

Everyone knows that the Sun is massive but let’s have a look at just how big it is and few other interesting facts.

The diameter of the Sun is 1.391016 Million km

  • That’s a diameter 10 times larger than that of Jupiter!
  • Or to put that in perspective, that’s about 110 times the diameter of Earth!

That’s just diameter… The total volume of the sun is 1.4 x 1027 m3

  • That’s 1,4,000,000,000,000,000,000,000 cubic km!

Jupiter x 985

  • The sun could fit around 985 planets the size of our largest planet, Jupiter, inside of it.

Earth x 1,300,000

  • If you squashed them to ensure there was no wasted space you could fit about 1,300,000 Earths inside of the Sun!

The Sun accounts for 99.86% of the mass in the solar system.

  • It has a mass of around 330,000 times that of Earth. It is three quarters hydrogen and most of its remaining mass is helium.

The Sun is still growing.

  • The Sun will continue to burn for about 130 million years after it burns through all of its hydrogen, instead burning helium. During this time it will expand to such a size that it will engulf Mercury, Venus, and Earth. When it reaches this point, it will have become a red giant star.

The Sun will eventually be about the size of Earth.

  • Once the Sun has completed its red giant phase, it will collapse. It’s huge mass will be retained, but it will have a volume similar to that of Earth. When that happens, it will be known as a white dwarf.

The Sun travels incredibly fast.

  • The Sun travels at about 220 km per second. It is around 26,000 light-years from the galactic centre and it takes the Sun approximately 250 million years to complete one orbit of the centre of the Milky Way.

It takes eight minutes for light reach Earth from the Sun.

  • The average distance from the Sun to the Earth is about 150 million km. Light travels at 300,000 km per second so dividing one by the other gives you 500 seconds – eight minutes and twenty seconds.

Planetary Facts

Let’s have a look at some interesting facts about the neighbours in our solar system.

Mercury

  • Mercury is named after the Roman god of merchants and travellers.
  • Mercury does not have any moons or rings.

The Milky Way

Our solar system existing inside of a collection of solar systems called a “Solar Neighbourhood”. A galaxy is made up of millions of these Solar Neighbourhoods. Ours is inside of the Milky Way galaxy which is just one of hundreds of millions, possibly billions of galaxies that make up the universe! Feeling small yet?

100,000 Light Years across

  • A light year is unit of measurement to measure distance. It is equivalent to the distance that light travels in one year. Keep in mind that it take light 8 minutes to travel from the Sun to Earth. Now try and get your head around how big the Milky Way is!

100 – 400 Billion Stars

  • The Milky Way contains between 100 – 400 billion stars. Our Sun is one such star. Just like our sun, many of these stars are orbited by planets which form solar systems.

13.6 Billion Years

  • The Milky Way is approximately 13.6 billion years old and began life as a series of dense regions not long after the Big Bang.

Many shapes and sizes

Galaxies come in many different shapes and sizes. These formations are broken in to 4 main categories, Elliptical, Normal Spiral, Barred Spiral and Irregular. These categories are then divided into sub-classifications. Our Milky Way is classified as an SBc Barred Spiral galaxy.
