THE SUN AND THE SOLAR SYSTEM.
This Vast universe has many galaxies. The galaxy we belong to is called the Milky Way. A galaxy consists of millions of stars, and the Sun is one of them.
The Sun and its family of eight planets and pieces of rocks and dust, together form the solar system. The eight planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, and Saturn. Uranus and Neptune.
The Sun gives us warmth, light, and energy. It is a huge ball of hot gases. It is also the only source of light and heat in the solar system. The energy we get from the Sun is called solar energy. The Sun is at the center of the solar system, and all the planets revolve around it. Green plants on Earth use this solar energy to make food. The Sun is a star, but have you ever wondered why it looks bigger than other stars? Sirius, which is twenty times brighter than the Sun, looks much smaller because it is farther away from Earth. Sun, looks much smaller because it is farther away from the Earth.
What is at the center of the solar system?
The Moon
The Earth
The Sun
Mars

Sirius is twenty times ______ than the Sun.
Match the following
The Sun
A star
Solar energy
essential for plants to make food
Green plants
make food using solar energy
Planets
Revolve around the Sun
Sirius
Twenty times brighter
The Sun is a huge ball of hot gases. (True/False)
Solar energy is the energy we get from the Moon. (True/False)
The Sun is at the center of the solar system. (True/False)
Green plants on Earth use solar energy to make water. (True/False)
Sirius looks smaller than the Sun because it is farther away from Earth. (True/False)
Planets
The eight planets that are part of our solar system move around the Sun, in
a fixed elliptical path. This movement is called revolution. The path is called
orbit. The planets and their moons also spin on an imaginary line called axis.
Planets do not have any light of their own. They get their light and warmth
from the Sun. Mercury is the closest planet to the Sun. Venus is the hottest
planet in the solar system. Neptune is farthest from the Sun and the coldest
planet in the solar system. We can group the planets in two simple ways:
A. by composition
B. by size
Composition
Rocky Planets: (Mercury, Venus, Earth, Mars): These planets are made of rock, and
metal. They are heavy and move slowly. They have few moons and do not have gaseous rings around them:
Which planet is the closest to the Sun?
Mars
Venus
Mercury
Jupiter
Do rocky planets have gaseous rings around them?
Yes
No
Sometimes
Depends on the size
How can planets be grouped?
By color
By composition
By distance from the sun
By shape
What are rocky planets made of?
Gas and ice
Rock and metal
Liquid and gas
Dust and ice
What do the eight planets in our solar system revolve around?
The Moon
The Earth
The Sun
Mars
What is the imaginary line called on which planets and their moons spin?
Orbit
Equator
Axis
Pole
Where do planets get light and warmth from?
Stars
Moon
Black holes
Sun
What is the movement of planets around the Sun called?
REVOLUTION
What is the path called that planets follow around the Sun?
Which planet is the closest to the Sun?
Which planet is the hottest in the solar system?
Which planet is the farthest from the Sun?
What are rocky planets made of?
rocks and metals

This movement of planets around the Sun is called ______.
revolution
The planets and their moons spin on an imaginary line called an ______.
Planets get their light and warmth from the ______.
Mercury is the ______ planet to the Sun.
Match the following
Revolution
Movement around the Sun
Orbit
Path of the planets
Axis
Imaginary line for spinning
Mercury
Closest to the Sun
Neptune
Farthest from the Sun
(True/False) The planets move around the Sun in a fixed elliptical path.
(True/False) The movement of planets around the Sun is called orbit.
(true/false) Planets have their own light.
Venus is the closest planet to the Sun. (True/False)
Neptune is the coldest planet in the solar system. (True/False)
Gaseous Planets (Jupiter, Saturn, Uranus, Neptune): These are mainly made up of gases which make them light (like a big air balloon). These planets move quickly, and have many moons and rings around them. The rings around Saturn are beautiful to look at.
Size:
Small Planets (Mercury, Venus, Earth, Mars): These planets are small in size and
are referred to as Lesser Planets because they are tiny. Mercury is the smallest
planet in the solar system.
Why are Small Planets like Mercury, Venus, Earth, and Mars referred to as Lesser Planets?
Due to their small size
Due to their distance from the Sun
Due to their lack of moons
Due to their unique compositions
What is particularly beautiful to observe about Saturn?
Its moons
Its atmosphere
Its rings
Its surface
What are Gaseous Planets mainly made up of?
Rocks
Water
Gases
Ice
Which planet is the smallest in the solar system?
Mercury
Venus
