2. WHAT IS SOLAR SYSTEM?
• Our solar system consists of our star, the Sun, and everything bound to
it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn,
Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons;
and millions of asteroids, comets, and meteoroids.

4. MERCURY
Mercury is the smallest planet in
the Solar System and the closest to
the Sun. Its orbit around the Sun
takes 87.97 Earth days, the shortest
of all the Sun's planets.
Distance from Sun: 58 million km
Radius: 2,439.7 km
Surface area: 74.8 million km²
Mass: 3.285 × 10^23 kg (0.055 M⊕)
Orbital period: 88 days
Coordinates: RA 13h 28m 29s | Dec -
7° 34′ 41″

5. VENUS
Venus is the second planet from the
Sun. It is sometimes called Earth's
"sister" or "twin" planet as it is almost
as large and has a similar composition.
As an interior planet to Earth Venus, like
Mercury, appears in Earth's sky never
far from the Sun, either as morning star
or evening star.
Distance from Sun: 108.2 million km
Radius: 6,051.8 km
Surface area: 460.2 million km²
Density: 5.24 g/cm³
Mass: 4.867 × 10^24 kg (0.815 M⊕)
Length of day: 116d 18h 0m

6. EARTH
Our home planet Earth is a rocky, terrestrial
planet. It has a solid and active surface
with mountains, valleys, canyons, plains
and so much more. Earth is special because
it is an ocean planet. Water covers 70% of
Earth's surface.
Earth's atmosphere is made mostly of
nitrogen and has plenty of oxygen for us to
breathe. The atmosphere also protects us
from incoming meteoroids, most of which
break up before they can hit the surface.

7. mars
Mars is the fourth planet from the Sun and
the second-smallest planet in the Solar
System, being larger than only Mercury. In
the English language, Mars is named for
the Roman god of war.
Distance from Sun: 227.9 million km
Radius: 3,389.5 km
Surface area: 144.8 million km²
Mass: 6.39 × 10^23 kg (0.107 M⊕)
Density: 3.93 g/cm³
Moons: Phobos, Deimos

jupiter
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, but slightly
less than one-thousandth the mass of the
Sun.
Distance from Sun: 778.5 million km
Radius: 69,911 km
Surface area: 61.42 billion km²
Mass: 1.898 × 10^27 kg (317.8 M⊕)
Density: 1.33 g/cm³
Age: 4.603 billion years
Moons: Europa, Io, Ganymede, Callisto, A
malthea, Adrastea, MORE

9. 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 and a half
times that of Earth. It has only one-eighth
the average density of Earth; however,
with its larger volume, Saturn is over 95
times more massive.
Distance from Sun: 1.434 billion km
Radius: 58,232 km
Surface area: 42.7 billion km²
Mass: 5.683 × 10^26 kg (95.16 M⊕)
Density: 687 kg/m³
Age: 4.503 billion years
Moons: Titan, Enceladus, Mimas, Dione, Iap
petus, Tethys, Hyperion, MORE

10. uranus
Uranus is the seventh planet from the Sun.
Its name is a reference to the Greek god of
the sky, Uranus, who, according to Greek
mythology, was the great-grandfather of
Ares, grandfather of Zeus and father of
Cronus. It has the third-largest planetary
radius and fourth-largest planetary mass in
the Solar System.
Distance from Sun: 2.871 billion km
Orbital period: 84 years
Radius: 25,362 km
Surface area: 8.083 billion km²
Mass: 8.681 × 10^25 kg (14.54 M⊕)
Density: 1.27 g/cm³
Moons: Miranda, Titania, Oberon, Ariel, Um
mbriel, Puck, Cressida, MORE

11. neptune
Neptune is the eighth planet from the Sun
and the farthest known solar planet. In
the Solar System, it is the fourth-largest
planet 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.
Distance from Sun: 4.495 billion km
Orbital period: 165 years
Radius: 24,622 km
Surface area: 7.618 billion km²
Length of day: 0d 16h 6m
Mass: 1.024 × 10^26 kg (17.15 M⊕)
Moons: Triton, Thalassa, Hippocamp, Nere
eid, Galatea, Despina, MORE

12. sun
Our Sun is a 4.5 billion-year-old star – a hot
glowing ball of hydrogen and helium at the
center of our solar system. The Sun is about 93
million miles (150 million kilometers) from Earth,
and without its energy, life as we know it could
not exist here on our home planet.
The Sun is the largest object in our solar system.
The Sun’s volume would need 1.3 million Earths
to fill it. Its gravity holds the solar system
together, keeping everything from the biggest
planets to the smallest bits of debris in orbit
around it. The hottest part of the Sun is its core,
where temperatures top 27 million degrees
Fahrenheit (15 million degrees Celsius). The Sun’s
activity, from its powerful eruptions to the
steady stream of charged particles it sends out,
influences the nature of space throughout the
solar system.

13. WHO DISCOVERED THE
SOLAR SYSTEM?
Born in 1564, Italian astronomer Galileo
Galilei's observations of our solar system and the
the Milky Way have revolutionized our
understanding of our place in the Universe.

14. Why is it Called the Solar System?
14
There are many planetary systems like
ours in the universe, with planets
orbiting a host star. Our planetary
system is called “the solar system”
because we use the word “solar” to
describe things related to our star,
after the Latin word for Sun, "solis."
