Why are Moons Important to Planets

why are there moons


Well, the majority of moons are “grabbed” by other rocky bodies or coalesced dust due to gravity. 

Therefore, there are typically more moons on larger bodies.

Theoretically, planets can “acquire” the moon in a number of different ways. The most popular ones are

1) The moon was created at the same time as the planet and is almost entirely composed of the same material.

2) Object that is relatively foreign enters planet’s orbit.

Our moon was created by Theory 1; the only deviation is that the moon was created within a year of the collision between Earth and Thea, a Mars-sized object.

We must comprehend the formation of planets in order to comprehend the formation of moons.

We must be aware of the formation of the solar system in order to comprehend the formation of planets.

We must be aware of the beginning point where it all began in order to comprehend how the solar system was discovered.

Initially, the entire solar system was literally just a cloud of dust.

Around our enormous neighborhood, there was a cloud of dust left over from a few distant supernovae.

This dust and gas cloud was then thought to have started spinning as a result of a supernova.

Thus, the comparatively flat disc of dust was created. Materials heated up as they collided.

Rocks were formed when larger rocks formed as smaller rocks merged. 

The Sun was created when the material density in the dust cloud was extremely high.

Planets hadn’t yet been formed.

Moons weren’t yet present.

Except for the sun, there was nothing around you at that time.

There are indeed small rocks, but they will eventually grow to be larger.

Over time, they grow into sizable rock chunks with their own substantial mass.

Meanwhile, the sun was happily going about his business in the distance, exerting a gravitational field that affected the solar system’s surrounding dust and races.

They were circling the sun. 

These rocks eventually combine into a larger mass of rocks through countless violent collisions and clashes between smaller and smaller rocks.

Things are so violent that when these rocks collide, they turn into liquid. 

They eventually sphered out since they were malleable and spinning.

You start observing the first indications of planet formation!

Even after this, there were still many derbies in the Solar System, and these rocks were hurtling in the direction of the young planets and diving bombing them in the Kamikaze fashion.

Sometimes larger rocks, up to half the size of planets, would view planets as pins in a bowling alley and themselves as the bowling ball, shooting straight down toward the planet and crashing into it!

Massive heights in space are reached by the derbies of these enormous collisions, which are caused by both objects.

There’s a chance that the centers of two bodies will merge to form one, leaving behind debris on every continent.

These derbies might orbit the earth.

You now have a tiny replica of the “Sun with debris of gas and dust orbiting around sun” phenomenon.

There will be moon(s) from the orbiting debris field around planets, much like how planets form from this Sun and debris of gas and dust.

If the planet is so massive that it keeps tearing its moon apart, the debris may collide and coalesce into what we know as Earth’s moon, or it may become a ring around the planet like Jupiter.

And one of the most notable ways that moons are formed is in this manner.

What Would Happen If There Was No Moon

Now, it’s difficult to assess what would occur if moons weren’t present.

Every moon is distinctive. Each planet is distinct. The satellite systems of each planet vary.

Tidal forces won’t exist in the ocean if you’re referring to earth.

Leave that aside; it’s possible that life on land never evolved. 

Water recedes during low tides, giving the amphibians a chance to walk on land and spend some time there.

Terrestrial life began as a result of their adoption of land-based living.

And if that weren’t enough, our Moon gives us a wobble-free orbit that is stable.

This entails controlled seasons and a lack of abrupt temperature changes around the globe.

This implies that life as we know it may not have formed at all if there had been no moon and these conditions existed.

The moon shields the planet from asteroids and other foreign objects.

Since the other 7 planets are all dead, the effects on the moons of other planets may not be as dramatic.

No exciting tale of life and its perils will be available.

Other physical phenomena (related to their orbits and wobble) might exist that aren’t as common in the planets as what we see right now.


Why does Mercury and Venus do not Have a Moon

Mercury and Venus are the only planets in the Solar System without moons.

The Sun is too close to them. Most likely there is at least one moon on every other planet.

Any moon that is too far from these planets will have an unstable orbit and will be swallowed up by the Sun.

They would be wiped out by tidal gravitational forces if they were too near these planets.

Mercury is not only the smallest planet, but it is also the one that is closest to the Sun, which reduces the size of its Hill Sphere, which is the sphere in which a planet can have moons.

The Sun will yank away any Mercurian moons.

But Venus is interesting. Since Earth has a moon, their masses are comparable.

Venus is closer to the Sun than Earth is, but its Hill Sphere should still be large enough for it to have one or two moons.

It’s possible that Venus once had a moon from colliding with another proto-planet, just like Earth did to get its moon, back when the Solar System was still very young.

Venus experienced a second significant collision, in contrast to Earth. 

Its rotation was reversed to a retrograde direction as a result of this collision.

Assuming the moon’s orbit is pro grade, the moon’s orbit will get smaller due to tidal deceleration, and Venus’ rotation will slow down (since Venus rotates retrograde; if Venus rotates in the same direction as the moon’s orbit but rotates faster than the moon’s orbital period, it will go faster).

Venus was left with a slow, retrograde rotation and no moons after the moon collided with it.
