Top 7 Facts About The Solar System

Top 7 best Facts About The Solar System | Daily Nature Facts

The solar system was established roughly 4.6 billion years ago when a massive molecular cloud collapsed. The Sun and a flat disc of dust formed from the mass at its centre. This finally resulted in the formation of the planets and other components of the solar system.

Here are the top 7 facts about the solar system;

1. The Solar System formed 4.6 Billion years ago

The Solar System evolved from a cloud of gas and dust known as the solar nebula 4.6 billion years ago. Facts About The Solar System It was most likely generated by a shock wave from a nearby supernova (big star) explosion. The Sun originated in the middle, followed by the planets.

2. The Sun is 93 million miles from the Earth

That’s the equivalent of 1000 visits to Australia! Facts About The Solar System, Despite its great distance, the Sun’s light only takes 8 minutes to reach Earth.

3. Planets Are Made of Rock or Gas

Our solar system’s eight planets are classified into two groups: the inner planets, Mercury, Venus, Earth, and Mars, which are mostly formed of rock and metal, and the outer planets, Jupiter, Saturn, Uranus, and Neptune, which are mostly made of hydrogen, helium, and other gases. Facts About The Solar System Despite being referred to be gas giants, their gases are compressed into liquid metal or rock due to extreme heat and pressure towards their centres.

4. There Are 100 Billion Solar Systems In Milky Way Galaxy

The solar system was thought to symbolise the whole cosmos in ancient times, and the planets were thought to be ‘wandering stars’ circling the Earth with the Sun and stars. The Earth was eventually added to the list of planets once the scientific revolution began in 1543, but astronomers still knew of just one solar system in the cosmos until recently. Facts About The Solar System Over 4,000 planets circling faraway stars have been discovered in the last 17 years or so, and astronomers now estimate that there may be as many as 100 billion solar systems in our own Milky Way galaxy alone.

5. The largest atmospheric vortex in the Solar System,

The Great Red Spot on Jupiter, the Solar System’s greatest atmospheric vortex, is larger than Earth. It has been raging for almost 350 years, but it appears to be dying down. It’s been going on for at least two centuries. It is unknown how far the vortex stretches underneath the apparent cloud tops.

We looked at the gravitational signature of the GRS using data from the Juno spacecraft’s 12 contacts with the planet, including two straight overflights of the vortex. Facts About The Solar System The presence of the GRS induced a change in the spacecraft’s line-of-sight velocity due to localised density anomalies. Using two different approaches to infer the GRS depth, which yielded consistent results, we conclude that the GRS is contained within the upper 500 kilometres of Jupiter’s atmosphere.

6. The planet with the most similar size and gravity to Earth is Venus, but it is also the hottest.

It is a cloud-covered planet with the name of a love goddess who is frequently referred to be Earth’s twin. But when you get a little closer, Venus becomes infernal. The second planet from the Sun, our closest planetary neighbour, with a surface temperature high enough to melt lead. The Sun appears as only a smudge of light from the surface due to the dense atmosphere.

In some respects, Venus is more like Earth’s opposite than its twin since it spins in the other direction, has a day that is longer than its year, and has no discernible seasons. It may have once been an ocean world that could support life, similar to Earth, but that was at least a billion years ago. Facts About The Solar System All surface water was converted to vapour due to a runaway greenhouse effect, which progressively vented into space. The present-day surface of volcanic rock is blasted by high temperatures and pressures.

7. Only three moons in the outer Solar System are geologically active: Enceladus, Io, and Triton.

Enceladus had two flybys by the Cassini spacecraft, which revealed that the moon contains a significant atmosphere. Researchers speculate that there may be volcanism, geysers, or gases that are exiting the interior via the surface based on data from the spacecraft’s magnetometer.

The significance of these discoveries cannot be overstated since they provide an update on the last Voyager flyby in 1981, which was so far away that no atmosphere could be seen. Facts About The Solar System It is clear from the discovery of an atmosphere, a magnetic field, and the possibility of liquid water below the surface that Enceladus meets the conditions necessary to support life.

The three current scientific prerequisites for the emergence of life are energy, a complex chemical environment, and liquid water. Enceladus is the only object in our solar system, aside from Earth, Facts About The Solar System where all of these things are now present. Although they haven’t verified it, scientists believe that Europa, Jupiter’s moon, may also meet all three requirements.

Enceladus is too cold for liquid water, but since it contains ammonia, a natural antifreeze, it would be possible for liquid water to exist below the surface without freezing. Analysis of the plumes indicates that the acidity does not exclude the potential for life. Facts About The Solar System The Cassini spacecraft did find additional sophisticated organics and chemicals in some of the plumes.
