C
Voyager - I

D
Galileo

Solution
Question 7
1 / -0

Which of the following is correct?

A
1 light year $$=6.3\times {10}^{4}$$ astronomical unit

B
1 parsec $$=3.26$$ light year

C
$$1$$ fermi$$={10}^{-15}m$$

D
All of these

Solution

$$1$$ light year $$=6.3 \times 10^4$$ astronomical units.
Thus option (A) is correct.
Question 8
1 / -0

The approximate tilt of the moons orbit is:

A
$$15^{\circ}$$

B
$$10^{\circ}$$

C
$$5^{\circ}$$

D
$$1^{\circ}$$

Solution

The Moon's orbit about the Earth lies in a plane which is tilted by about 5.15° with respect to the plane of the Earth's orbit about the Sun. (If this tilt was zero, we would have total solar and lunar eclipses every month!)
Question 9
1 / -0

In which planet sun sets in east?

Saturn

B
Venus

C

B
The moon was formed with the solar system from clouds of gas and dust

C
A giant asteroid hit the Earth and blew off a large piece which was caught in orbit

D
The moon was formed elsewhere and was caught by Earths gravity as it passed by

Solution

Most accepted theory of moon formation is giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet (like asteroid) about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.
Hence Option D
