Sirius is the brightest star visible from Earth. It can sometimes be seen during daylight hours under optimal conditions with a clear sky. The Sun is the star at the center of the solar system. It is a spherical mass of hot plasma and magnetic fields that is over 1 million kilometers in diameter and weighs 330,000 times more than Earth. Certain stars appear close to the Earth's axis of rotation and can be seen directly overhead from the North or South Pole, these are known as pole stars or the North Star.

2.  Sirius is the brightest star in the night sky.
 Sirius can even be observed in daylight with
the naked eye under the right conditions.
Ideally, the sky should be very clear, with the
observer at a high altitude, the star passing
overhead, and the Sun low down on the
horizon

3.  The Sun is the star at the centre of the solar
system
 It is almost perfectly spherical and consists of
hot plasma with magnetic fields
 It has a diameter of about 1,392,000 km, and
its weight is 330,000 kg It is 109 times that
of Earths weight

4.  A pole star is a visible star, especially a
prominent one, that is approximately aligned
with the Earth's axis of rotation; that is, a star
whose apparent position is close to one of
the celestial poles, and which lies
approximately directly overhead when viewed
from the Earth's North Pole or South Pole
 Pole Star is also known as the North Star.

5.  The stars forming a group that recognisable
shape is called a constellation
 Some of the examples are great
bear,orion,cassiopeia,leo major etc

6.  VY Canis Majoris is the largest known star
and also one of the most luminous. It is a
red hypergiant in the constellation Canis
Major.
 Placed at the center of our solar system

7. Stars are huge balls of glowing gas.
Deep inside a star, a gas called
hydrogen is changed into
a gas called helium.

8.  In some cultures, the stars represent part of the
cosmos, such as the heavens or the home of the
gods, or a path between the earth and another
world
 The Paiute of North America describe the stars as
the children of the sun and moon. Because the sun
loves to eat his children, the stars disappear
whenever he rises above the horizon. However,
the moon, their mother, often dances happily
across the sky with the stars.

To the Yakut of Siberia, the stars are crystal
windows that allow the gods to look down at earth
