It’s that time of year again, when the clocks go back and the nights get longer! Whilst it may sound gloomy, it can be a great time to see the stars in the sky. That is of course if it’s not pouring down with rain. In the hope that we do have some clearer nights, we’ve listed the top best space facts so that you and your little one can enjoy looking up out into the galaxy!
Our solar system is over 4.5 billion years old and lives within the Milky Way. Scientists have discovered over 500 solar systems in our Milky Way. They have also said that there could be 100 million other solar systems in the entire galaxy. This means there could be a planet just like the Earth that we have yet to discover!
The Sun is the closest star to the Earth. Although it may seem close as we can feel its warmth during the summer months, it is actually 150 million km away. If we were to travel in an aeroplane it would take 19 years to get there. Not sure it’s quite worth the trip!
The Sun shines by burning its own fuel, making it slowly lose power and size. As the Suns size slowly decreases, it causes the Earth to very slowly slip away from the pull, gradually making us travel further away. Don’t worry though, we are moving at such a slow rate of 15cm per year we won’t be going anywhere anytime soon!
Venus is hotter than Mercury, even though it’s further away from the Sun. This is because there are higher levels of carbon dioxide trapping the heat in Venus’ atmosphere. The temperature on Venus is 462°C! That’s what we mean when we say we want a hot holiday!
Venus is the 2nd brightest natural object in the night sky after the Moon. It’s often visible during a clear night and sometimes even in the day! Here’s a free app that help locate Venus in the sky! Link.
The first person to walk on the moon was Neil Armstrong in July 1969. The footprints on the moon made by the astronauts’ boots will be there for 100 million years. This is because the moon has no atmosphere, so there’s no wind or water to sweep the footprints away!
A rocket that carries people up to space can take 5 years to make! Rockets need to travel at 5 miles per second in order to reach space, which means that they can travel 18,000 miles per hour. Now that’s fast!
There are more stars in the universe than grains of sand on all the beaches on the Earth. That’s at least a billion trillion! However, the human eye is only able to see 5000 stars in the sky. The largest star in the universe is 1,700 times bigger than our Sun. How crazy is that?
It’s fair to say that outer space is incredibly big, with much of it yet to be explored! Scientists are discovering new things every day. It’s exciting to see what the next big discovery will be!
