Mercury & Venus are the only 2 planets in our solar system that have no moons.

Mercury & Venus Don't Have Moons - 100 Space Facts

In total, there are 176 confirmed moons that orbit the planets in our solar system, with some of them being bigger than Mercury itself!

If a star passes too close to a black hole, it can be torn apart.

Star passing a black hole - 100 Space Facts

For 20 years, a team of astronomers observed a star at the center of our galaxy orbiting a black hole.

The star has now got close enough to the black hole for “gravitational redshift” to occur which is where the star’s light loses energy as the black hole’s gravity intensified.

The hottest planet in our solar system is Venus.

Venus is the hottest planet

Most people think that this would be Mercury, as it is the closest planet to the sun.

However, Venus has a lot of gasses in its atmosphere which creates a “Greenhouse Effect” that causes a constant temperature of 864° Fahrenheit (462° Celsius) everywhere on the plant’s surface.

Our solar system is 4.6 billion years old.

Age of the Solar System - 100 Space Facts

Well, give or take 30 million years(ish). Accurately speaking, it is 4.571 billion years old.

Scientists estimate that in about 5 billion years, our Sun will expand becoming a Red Giant.

In about 7.5 billion years its expanding surface will swallow up and engulf the Earth.

Enceladus, one of Saturn’s smaller moons, reflects 90% of the Sun’s light.

Enceladus reflects 90% of light

Because Enceladus’ icy surface reflects sunlight rather than absorbing it, temperatures reach as low as -394° Fahrenheit (-201° Celsius).

The highest mountain discovered is the Olympus Mons, which is located on Mars.

Olympus Mons compared to Mount Everest

Its peak is 16 miles (25 km) high, making it nearly 3 times higher than Mount Everest.

And not only is it tall, but it’s also 374,015 ft² (114,000 m²) wide – that’s an area the size of Arizona!

The Whirlpool Galaxy (M51) was the first celestial object identified as being spiral.

Whirlpool Galaxy M51

The grand, spiraling arms of the Whirlpool Galaxy are made up of long lanes of stars and gas, sprinkled with lots of space dust.

These arms act as star formation factories, compressing hydrogen gas and creating clusters of new stars.

A light-year is the distance covered by light in a single year.

What is a light year?

Light moves at the velocity of about 186,411 miles (300,000 km) a second.

So one light-year equates to roughly 5,903,026,326,255 miles!

The Milky Way galaxy is 105,700 light-years wide.

Milky Way length

It would take a modern spacecraft 450,000,000 years to travel to the center of our galaxy!

You can read more unbelievable space facts with this list of Milky Way facts!

The Sun weighs about 330,000 times more than Earth.

Weight of the Sun

It is about 109 times the diameter of Earth and is so large the Earth could fit inside the sun about 1,300,000 times over!

In fact, the sun is so gigantic that it contains 99.85% of all mass in our solar system.

Footprints left on the Moon won’t disappear as there is no wind.

Footprints on the moon

But wait a minute… if there’s no wind to blow them away then why is the flag blowing? Well, it actually wasn’t blowing.

That rippling you see is because of a stubborn telescopic horizontal rod that the astronauts were struggling to remove from the flag’s upper hem.

Still unsure whether we’ve walked on the Moon? Here are 5 common Moon landing myths debunked.

Because of lower gravity, a person who weighs 220 lbs on Earth would weigh 84 lbs on Mars.

There are 79 known moons orbiting Jupiter.

Moons orbiting Jupiter

Jupiter is the planet in our solar system with the most moons, and it also has the largest moon in our solar system.

That moon is called Ganymede and is 33,279 miles (5,262 km) in diameter – that’s bigger than Mercury and it is visible with just a pair of binoculars!

The Martian day is 24 hours 39 minutes and 35 seconds long.

The Martian day length

So you’d therefore assume there are less days in a year on Mars than Earth, right? Wrong!

Because Mars orbits the sun slower than the Earth, there are actually 687 Martian days in a Martian year!

NASA’s Crater Observation and Sensing Satellite (LCROSS) found evidence of water on the Earth’s Moon.

Whilst water cannot exist on the Moon’s surface under its current conditions, scientists believe water ice could survive within the cold, permanently shadowed crates at the Moon’s two poles.

The Sun makes a full rotation once every 25 – 35 days.

The Sun rotation

So for us on Earth, one full rotation equals one full day. However, our gargantuan sun takes 25 – 35 Earth days to make one full rotation!

Earth is the only planet not named after a God.

Earth isn't named after a God

Nobody knows how the Earth got its name; all we know is that it is derived from an amalgamation of both the Old English and Old Germanic words for “ground”.

Due to the Sun and Moon’s gravitational pull, we have tides.

The Moon controls our tides

This is because the Moon’s tidal force causes the Earth – and the water on it – to bulge out on the side closest to the Moon.

These bulges are what cause the world’s high tides.

Pluto is smaller than the United States.

Pluto size comparison

If you were to walk around the equator of Pluto it would be the same distance as walking from London to Denver (well, give or take 56 miles).

According to mathematics, white holes are possible, although as of yet we have found none.

White Hole

A white hole is a hypothetical region of space-time which can’t be entered from the outside, although matter and light can escape from within.

Basically, it’s the reverse of a black hole.

There are more volcanoes on Venus than any other planet in our solar system.

Volcanoes on Venus

There are more than 1,600 major volcanoes across the surface of Venus, including a 5 mile (8 km) high volcano called Maat Mons.

However, none of these volcanoes are known to be erupting at present and most are probably long extinct.

Uranus’ blue glow is due to the gases in its atmosphere.

Uranus' blue glow

Uranus’ atmosphere is made up of hydrogen, helium and methane.

The methane in Uranus’ upper atmosphere filters out all the red light from the Sun but reflects the Sun’s blue light back into space, giving it its blue appearance.

Enjoying our space facts? If you’re interested in learning more, we have more interesting facts about Uranus.

In our solar system that are 4 planets known as gas giants: Jupiter, Saturn, Uranus & Neptune.

The four gas giants

A gas giant is a large planet that is made up mostly gases like hydrogen and helium, and has only a relatively small rocky core.

Uranus has 27 moons that have been discovered so far.

It has 5 large moons, and 22 small moons. Titania is the largest of Uranus’ moons and is the eighth largest moon in our solar system with an average diameter of 980.5 miles (1,578 kilometers).

Because of its unique tilt, a season on Uranus is equivalent to 21 Earth years.

Uranus' tilt

Also the 97.77 degrees tilt on Uranus’ axis means that a day there only last 17 hours, 14 minutes and 24 seconds.

Neptune’s moon, Triton, orbits the planet backwards.

Triton & Neptune Rotation

Triton is the only large moon of any of the planets that does this.

This is known as a retrograde orbit and astronomers are unsure as to why Triton orbits Neptune this way.

Triton is gradually getting closer to the planet it orbits.

Triton Moon

Scientists believe that when Triton eventually gets too close to Neptune, it will be torn apart by the planet’s gravity and could potentially create another ring around Neptune – giving it more rings than Saturn.

There are more stars in space than there are grains of sand in the world.

There are more stars than sand

There are 10 times more stars in the night sky than grains of sand on the Earth, with 70 sextillion stars being visible from Earth through a telescope.

To put that in numbers, 70 sextillion is this: 70,000,000,000,000,000,000,000.

Neptune takes nearly 165 Earth years to make one orbit of the Sun.

The time for Neptune to orbit the Sun

That’s equivalent to 60,190 Earth days to orbit the sun once! Neptune has a very slow orbital speed of 3.37 miles per second (5.43 km/s).

This means that since it was discovered in 1846, it has only completed just one orbit!

The International Space Station circles Earth every 92 minutes.

ISS Orbiting Earth

The speed of the ISS as it orbits Earth is roughly 17,150 miles per hour – that equates to 5 miles a second!

Stars twinkle because of the way light is disrupted as it passes through Earth’s atmosphere.

Why do stars twinkle?

Starlight is affected by the winds in our atmosphere as it enters, as well as being affected by different areas and temperatures.

This causes the light from each star to twinkle as we look at them.

We always see the same side of the Moon, no matter where we stand on Earth.

The moon from Earth

This is because the Moon rotates on its axis at the same rate that it rotates the Earth.

This is known as synchronous rotation or tidal locking.

There are three main types of galaxies: elliptical, spiral & irregular.
