The Solar System

The Sun contains 98.8 percent of the mass in the solar system because it is a massive ball of hot, glowing gases that make up most of the system's total mass. The Sun's gravity is strong enough to hold the planets, moons, asteroids, and other objects in orbit around it, which is why it contains the majority of the system's mass.

in this solar system you might search for microbial life on mars as some signs of life there have been detected recently.

You may also search for life on Europa (a moon of Jupiter) which may have water oceans below miles of ice.

There are a few other places in which life may exist but those theories are based on life forming in a different way to the other life that we know of.

The field of heliophysics studies the Sun and its interactions with Earth and other planets in the solar system. It involves understanding solar activity, solar wind, magnetic fields, and their impacts on the space environment surrounding the planets. Scientists use various instruments, satellites, and spacecraft to study these phenomena.

The amount of light a star produces can give insights into its temperature, size, and relative luminosity compared to other stars. It can also help astronomers determine the star's distance from Earth and its age.

The closest star system to our Sun is Alpha Centauri, which consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest to the Sun at a distance of about 4.24 light-years.

They are puffy, like cotton balls. Not in any any particular shape, just round(ish).
Gigantic white towers of cloud with dark grey bases, sometimes with flattened tops appearing like a pancake or an anvil
A cumulonimbus formation is tall and billowing, with an anvil-shaped top.
Cumulonimbus clouds have flat tops and bottoms, giving them an anvil-like appearance.
stormy weather, most likely low pressures system, and gusty... and occurs during a cold front. :D

The heliocentric model is the one that has the Sun at the centre and the Earth the third planet out. We don't use the heliocentric model of Copernicus with its circles and epicycles, that was superseded by Kepler's model, but we still have the Sun at the centre.

Saturn has very prominent rings around it, consisting of ice particles, rock debris, and dust. These rings are one of the most iconic features of the planet and easily visible from Earth through a telescope.

because they thought the moon dust was toixic and would die from exposure to it that's why in early manned space missions they had them go through a long decaotamination process after going to the moon.

The "Goldilocks planet" refers to a planet that is situated at just the right distance from its star to potentially support liquid water on its surface, which is a key factor for life as we know it. While there are candidates that fit this description in various solar systems, Earth is currently the only confirmed Goldilocks planet in our own solar system.

Mercury has the least variation in surface temperature among the planets in our solar system. This is because it has almost no atmosphere to trap heat, leading to very hot temperatures on the sunny side and very cold temperatures on the dark side.

The sun is 30000 chocolate unicorns times larger

We know next-to-nothing about the surface of Saturn. We can guess that something at least resembling gravel exists there, because it exists on Saturn's moon Titan.

The force that governs the motion of the solar system is primarily gravity. Gravity, which is the attractive force between objects with mass, keeps the planets in orbit around the Sun and maintains the structure and dynamics of the solar system.

During a quarter moon, we see half of the moon's surface lit up by the sun. This is because the angle between the sun, Earth, and moon creates a line where we see only half of the illuminated side.

That kind of depends on where you consider the boundary of "the solar system" to be.

It's currently in the "heliosheath" and will probably reach the heliopause... which is one reasonable definition of "outside the solar system"... within the next ten years or so. Voyager 1, which is further away and moving faster, is expected to reach this boundary in about 2015, but Voyager 2 reached the heliosheath significantly closer to the Sun than Voyager 1 did... this boundary appears to be "dented" in the direction that Voyager 2 is heading.

Voyager 2 is well outside what most non-scientists think of as "the solar system" already... it's over twice as far from the Sun as Pluto is, for example.

No new planets have been found near our Sun.

The latest discovery is a planet twice the size of Jupiter called Wasp 17. It lies about 1,000 light years from us.

None of the four outer planets, they all have rotational periods shorter than 24 hours. The dwarf planet Pluto has a rotational period of 6.4 days though.

A blue star has a spectral class of O. It is one of the largest types of star on the main sequence.

As the colour is based on the surface temperature, and not on size, there is no definitive size.

However, using Alntak (See related link) - a star in the constellation Orion - as an example of a blue star, we can expect a blue star to be around 20 times as big as our Sun. (See related question)

the inner planets (Mercury, Venus, Earth, Mars) all have rocky solid surfaces. The outer planets (Jupiter, Saturn, Uranus, Neptune) all have gaseous atmospheres and liquid surfaces. Pluto is very dense and has a rocky surface.

No, the Earth and the Sun are not in thermal contact in the traditional sense. The Sun emits electromagnetic radiation which carries heat and light to the Earth through space. The Earth absorbs this radiation and warms up as a result.

If the Earth was the size of a basketball, then the Moon would be about the size of a tennis ball in relative scale. The Moon is about 1/4 the diameter of Earth, so in this scenario, its size would proportionally shrink down as well.

The are probably many we haven't discovered yet. However currently there are five known dwarf planets.

As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
