*The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma
*The Sun's radius is about 695,000 kilometers (432,000 miles), or 109 times that of Earth. Its mass is about 330,000 times that of Earth.
*The Sun's atmosphere is composed of four parts: the photosphere (visible under normal conditions),
the chromosphere, the transition region, the corona and the heliosphere.
During a total solar eclipse, the photosphere is blocked, making the corona visible
The average temperature of the corona and solar wind is about 1,000,000–2,000,000 K
*Mercury is the smallest planet in our solar system. It's a little bigger than Earth's Moon.
*It is the closest planet to the Sun, but it's actually not the hottest,Venus is hotter.
*According to current theories, Mercury may have a solid silicate crust and mantle overlying a solid outer core,
a deeper liquid core layer, and a solid inner core
*Orbital period (sidereal) : 87.9691 d 0.240846 yr 0.5 Mercury synodic days
*Orbital period (synodic) : 115.88 d
*Distance of mercury from sun : 69.193 million km
#Venus is the second planet from the Sun. It is a rocky planet with a mass and size
#it completes a sidereal rotation, relative to the stars, in 243 Earth days.
Therefore it rotates slower than it is orbiting, having a solar year of 224.7 Earth days,
this results together with the retrograde rotation in having a solar day of 117 Earth days
#Venus has a dense atmosphere composed of 96.5% carbon dioxide, 3.5% nitrogen—both exist as supercritical
fluids at the planet's surface—and traces of other gases including sulfur dioxide
#Orbital period (sidereal) : 224.701 d 0.615198 yr 1.92 Venus solar day
#Orbital period (synodic) : 583.92 days
#venus current distance from sun : 107.76 million km
*Earth is the third planet from the Sun and the only place known in the universe where life has originated and found habitability
*Earth has a dynamic atmosphere, which sustains Earth's surface conditions and protects it from most meteoroids and UV-light at entry
. It has a composition of primarily nitrogen and oxygen. Water vapor is widely present in the atmosphere
*Earth is rounded into an ellipsoid with a circumference of about 40,000 km
*The atmospheric pressure at Earth's sea level averages 101.325 kPa (14.696 psi), with a scale height of about 8.5 km (5.3 mi).
*A dry atmosphere is composed of 78.084% nitrogen, 20.946% oxygen, 0.934% argon,
and trace amounts of carbon dioxide and other gaseous molecules.
Water vapor content varies between 0.01% and 4% but averages about 1%
*Orbital period (sidereal) : 365.256363004 d
*Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun.
*Mars is the fourth planet and the furthest terrestrial planet from the Sun.
The reddish color of its surface is due to finely grained iron(III) oxide dust in the soil, giving it the nickname "the Red Planet".
*Mars lost its magnetosphere 4 billion years ago,[101] possibly because of numerous asteroid strikes,[102] so the solar wind interacts directly with the Martian ionosphere,
lowering the atmospheric density by stripping away atoms from the outer layer
*Compared to Earth, its higher concentration of atmospheric CO2 and lower surface pressure may be why sound is attenuated more on Mars
*Auroras have been detected on Mars. Because Mars lacks a global magnetic field, the types and distribution of auroras there differ from those on Earth.
*Orbital period (synodic) : 779.94 d(2.1354 yr)
*Mars current distance from Sun : 250.62 million kms
*Jupiter is the fifth planet from the Sun and the largest in the Solar System.
*It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined,
and slightly less than one one-thousandth the mass of the Sun
*Jupiter is a gas giant, being primarily composed of gas and liquid rather than solid matter.
It is the largest planet in the Solar System, with a diameter of 142,984 km (88,846 mi) at its equator.
The average density of Jupiter, 1.326 g/cm3, is about the same as sugar syrup (syrup USP),and is lower than those of the four terrestrial planets.
*The atmosphere of Jupiter extends to a depth of 3,000 km (2,000 mi) below the cloud layers
*Jupiter is perpetually covered with clouds of ammonia crystals, which may contain ammonium hydrosulfide as well.
The clouds are located in the tropopause layer of the atmosphere, forming bands at different latitudes, known as tropical regions.
*Orbital period (synodic) : 398.88 d
*From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun.
*Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter.
It is a gas giant with an average radius of about nine and a half times that of Earth
*Saturn's interior is thought to be composed of a rocky core, surrounded by a deep layer of metallic hydrogen,
an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer
*The outer atmosphere of Saturn contains 96.3% molecular hydrogen and 3.25% helium by volume
*Saturn's atmosphere exhibits a banded pattern similar to Jupiter's, but Saturn's bands are much fainter and are much wider near the equator
*Orbital period (synodic) : 378.09 days
*Saturn is the sixth planet from our Sun (a star) and orbits at a distance of about 886 million miles (1.4 billion kilometers) from the Sun.
*Uranus is the seventh planet from the Sun and is a gaseous cyan ice giant.
*Most of Uranus is made out of water, ammonia, and methane in a supercritical phase of matter, which in astronomy is called 'ice' or volatiles.
*The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of 49 K (−224 °C; −371 °F) out of all Solar System's planets.
*Uranus's mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets.
*Its diameter is slightly larger than Neptune's at roughly four times that of Earth.
A resulting density of 1.27 g/cm3 makes Uranus the second least dense planet, after Saturn.
*Although there is no well-defined solid surface within Uranus's interior, the outermost part of Uranus's gaseous envelope that is accessible to remote sensing is called its atmosphere
*Orbital period (synodic) 369.66 days
*From an average distance of 1.8 billion miles (2.9 billion kilometers), Uranus is 19.8 astronomical units away from the Sun.
*Neptune is the eighth planet from the Sun and the farthest known planet in the Solar System. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet.
*It is 17 times the mass of Earth, and slightly more massive than its near-twin Uranus.
*Neptune's internal structure resembles that of Uranus.
*Its atmosphere forms about 5 to 10% of its mass and extends perhaps 10 to 20% of the way towards the core.
*At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium.[27] A trace amount of methane is also present. Prominent absorption bands of methane exist at wavelengths above 600 nm, in the red and infrared portion of the spectrum
* As with Uranus, this absorption of red light by the atmospheric methane is part of what gives Neptune its blue hue, although Neptune's blue differs from Uranus's milder light blue.
*Orbital period (synodic) 367.49 days
*Neptune orbits our Sun, a star, and is the eighth planet from the Sun at a distance of about 2.8 billion miles (4.5 billion kilometers).
