Asteroids are minor planets, especially those located in the inner Solar System. They are made up of rock and metals and are found predominantly in the asteroid belt between Mars and Jupiter. While small compared to Earth's moon, asteroids can be dangerous if they collide with Earth. The document provides details on the composition and types of asteroids, as well as some of the largest asteroids like Ceres and Pallas. It also discusses how studying asteroids can help us understand the origins of our solar system and life.

6. What is Asteroid?
•Asteroids are minor planets,
especially those of the inner Solar
System.
•They are also known as planetoids
or minor planets.

7. • The mass of all the asteroids is
less than that of Earth's moon.
But despite their size, asteroids
can be dangerous.

8. Where we can find Asteroids in our
Solar System?
Asteroids can be found anywhere in the
Solar System.
Asteroids are also can be found
between Mars and Jupiter known as the
“asteroid belt”...

12. Composition of Asteroids
• Most of Asteroids are made of
rock, but some are composed of
metals and other materials.

14. Exceptional
Asteroids

15. Ceres (dwarf Planet)
• the largest object in the asteroid
belt, which lies between the orbits
of Mars and Jupiter.

16. 2 Pallas
• the second asteroid to have been
discovered (after Ceres), and it is one of the
largest asteroids in the Solar System. With
an estimated 7% of the mass of the asteroid
belt, it is the third-most-massive asteroid,
being 10–30% less massive than Vesta.

17. 4 Vesta
• Vesta is the brightest asteroid visible
from Earth. Its maximum distance
from the Sun is slightly greater than
the minimum distance of Ceres from
the Sun,though its orbit lies entirely
within that of Ceres.

18. 10 Hygeia
• it is the largest of the class of
dark C-type asteroids with
a carbonaceous surface.

19. 704 Interamnia
• it is a very little-studied body. It is easily
the largest of the F-type asteroids, but
there exist very few details of its internal
composition or shape, and no light
curve analysis has yet been done to
determine the ecliptic coordinates of
Interamnia's poles (and hence its axial
tilt).

20. 52 Europa
• is the 6th-largest asteroid in
the asteroid belt, having an average
diameter of around 315 km. It is not
round but is shaped like a triaxial
ellipsoid of approximately
380x330x250 km.

21. 511 Davida
• It is a C-type asteroid, which means that it
is dark in colouring with a carbonaceous
chondrite composition.
• Davida is one of the few main-belt asteroids
whose shape has been determined by ground-
based visual observation.

22. 87 Sylvia
• the 8th-largest asteroid in
the asteroid belt. It is a member of
the Cybele group located beyond the
core of the belt (see minor-planet
groups). Sylvia is the first asteroid
known to possess more than one moon.

23. 65 Cybele
• is one of the largest asteroids in the Solar
System and is located in the outer asteroid
belt. It gives its name to the Cybele family
of asteroids that orbit outward from the
Sun from the 2:1 orbital
resonance with Jupiter.
• Cybele is a X-type asteroid, meaning that it
is dark in color and carbonaceous in
composition.

24. 15 Eunomia
• is a very large asteroid in the
inner asteroid belt. It is the largest of
the stony (S-type) asteroids, and
somewhere between the 8th-to-12th-
largest main-belt asteroid overall
(uncertainty in diameters causes
uncertainty in its ranking).

25. Uses of Asteroid in astronomy.
1. They will tell us about the origins
of our solar system.
2. They will help us understand more
about the origin of life.
3. We may want to mine near-earth
asteroids for metals.
4. They may someday threaten to
collide with Earth. (Future Study)

average diameter of around
315 km.
• 9-10. Give two (2) uses of Asteroid
in astronomy.
