41
The light coming from stars gives the idea of their ________
Discuss
Answer & Solution
Answer: Option D
Solution:
Stars emit colors of many different wavelengths, but the wavelength of light where a star's emission is concentrated is related to the star's temperature - the hotter the star, the more blue it is; the cooler the star, the more red it is.
42
Stars which appear single to the naked eye but are double stars when observed by a telescope, are known as ________
Discuss
Answer & Solution
Answer: Option C
Solution:
In observational astronomy, a double star or visual double is a pair of stars that appear close to each other as viewed from Earth, especially with the aid of optical telescopes. This occurs because the pair either forms a binary star (i.e. a binary system of stars in mutual orbit, gravitationally bound to each other) or is an optical double, a chance line-of-sight alignment of two stars at different distances from the observer.
43
Asteroids have their orbits between the planets ________
Discuss
Answer & Solution
Answer: Option C
Solution:
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The remaining bodies range down to the size of a dust particle.
44
Which one of the following statements is correct with reference to our solar system?
Discuss
Answer & Solution
Answer: Option A
Solution:
Earth is the fourth smallest of the planets-though in terms of the rocky planets, it's the largest-but it's the most dense.
45
The correct sequence of the following planets in terms of gravity, in the descending order is ________
Discuss
Answer & Solution
Answer: Option D
Solution:
The correct sequence of the planets in terms of gravity, in the descending order is Neptune, Saturn, Earth, Uranus.

Jupiter - 24.79 m/s2 (81.33 ft/s2)
Neptune - 11.15 m/s2 (36.58 ft/s2)
Saturn - 10.44 m/s2 (34.25 ft/s2)
Earth - 9.807 m/s2 (32.18 ft/s2)
Venus - 8.87 m/s2 (29.1 ft/s2)
Uranus - 8.69 m/s2 (29.4 ft/s2)
Mars - 3.711 m/s2 (12.8 ft/s2)
Mercury - 3.7 m/s2 (12.4 ft/s2)
46

1. Sirius
2. Venus
3. Mars
The correct sequence in decreasing order of their brightness is:
Discuss
Answer & Solution
Answer: Option D
Solution:
The correct sequence in decreasing order of their brightness is Venus, Sirius and Mars.
47
Which planet is considered as the Dwarf planet?
Discuss
Answer & Solution
Answer: Option C
Solution:
Pluto is considered as a dwarf planet. This is called so because it has not cleared its neighbourhood around its orbit. International Astronomic Unit declared it a Dwarf Panet in 2006. It orbits in a disc-like zone beyond the orbit of Neptune called the Kuiper belt, a distant region populated with frozen bodies left over from the solar system's formation.
48
Which of the following is the largest of the inner planets?
Discuss
Answer & Solution
Answer: Option D
Solution:
Earth is the third inner planet and the one we know best. Of the four terrestrial planets, Earth is the largest, and the only one that currently has liquid water, which is necessary for life as we know it.
49
Which of the following scientist had proven that every planet has an elongated path?
Discuss
Answer & Solution
Answer: Option D
Solution:
Kepler through his 'planetary law of motion' proved that every planet has an elongated path. Kepler had believed in the Copernican model of the solar system, which called for circular orbits, but he could not reconcile Brahe's highly precise observations with a circular fit to Mars' orbit – Mars coincidentally having the highest eccentricity of all planets except Mercury.
50
The orbit in which of the following planet is nearest to the Sun?
Discuss
Answer & Solution
Answer: Option C
Solution:
As compared to the orbit of the other given planets, Mars has nearest orbit to Sun. In the so-called perihelic opposition Mars is closest to the Sun and is particularly close to Earth: Oppositions range from about 0.68 AU when Mars is near aphelion to only about 0.37 AU when Mars is near perihelion.
