describe the Sun and its Planet with a well labelled diagram

The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit.
there are 8 planets in our solar system
1. Mercury -the smallest and innermost planet in the Solar System. Its orbit around the Sun takes 87.97 days, the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods.
Orbital period: 88 days
Distance from Sun: 57.91 million km
Length of day: 58d 15h 30m
Radius: 2,439.7 km
Mass: 3.285 × 10^23 kg (0.055 M⊕)
Surface area: 74.8 million km²
2.Venus-Venus is the second planet from the Sun. It is named after the Roman goddess of love and beauty. As the second-brightest natural object in the night sky after the Moon, Venus can cast shadows and can be, on rare occasion, visible to the naked eye in broad daylight.
Orbital period: 225 days
Length of day: 116d 18h 0m
Distance from Sun: 108.2 million km
Radius: 6,051.8 km
Surface area: 460.2 million km²
Equatorial rotation velocity: 6.52 km/h (1.81 m/s)
3.Earth-Earth is the third planet from the Sun and the only astronomical object known to harbor life. According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in 365.256 solar days, a period known as an Earth sidereal year. During this time, Earth rotates about its axis 366.256 times, that is, a sidereal year has 366.256 sidereal days.
4.Mars- Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being only larger than Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet".
5.Jupiter-Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Wikipedia
Moons: Europa, Io, Ganymede, Callisto, Amalthea, Dia, Valetudo, Carme, Adrastea, Himalia,
Orbital period: 12 years
Radius: 69,911 km
Surface area: 61.42 billion km²
Mass: 1.898 × 10^27 kg (317.8 M⊕)
Distance from Sun: 778.5 million km
6.Saturn-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 times that of Earth.[18][19] It only has one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive.[20][21][22] Saturn is named after the Roman god of wealth and agriculture; its astronomical symbol (♄) represents the god's sickle.
7.Uranus -is the seventh planet discovered in the Solar System that also led to the discovery of the last planet, Neptune they are both referred to as ice giants. Officially recognized in 1781 after many observations in the past, it is the third-largest planet of the Solar System.
8.Neptune-Neptune is the eighth and farthest known planet from the Sun in the Solar System. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth, slightly more massive than its near-twin Uranus.
