[NDA1995] They emit light due to extremely high temperature caused by friction while they are passing through earth’s atmosphere They are meteors They are a kind of a star They are the debris which got separated from a comet 2. While Venus is seen only for one to two hours either after sunset or before sunrise, Jupiter is seen for the whole night whenever it is visible in the sky. The reason for this is that: [CDS 2000] Venus is much smaller than Jupiter the orbit of Venus is inside the earth’s orbit whereas the orbit of Jupiter lies outside the orbit of the earth Venus is much closer to the earth than Jupiter Venus reflects lesser amount of sunlight than Jupiter 3. The constellations of stars appear at different positions in the sky at different times during night mainly: because earth rotates about its axis because of optical illusion because celestial bodies are changing their positions all the time because earth revolves round the sun 4. Consider the following astral bodies: 1. Sirius 2. Venus 3. Mars The correct sequence in decreasing order of their brightness is : [CDS 1999] 2, 1, 3 1, 2, 3 2, 3, 1 3, 2, 1 5. Twelve constellations referred to as zodiac are: [IAS 1989] none of these a group of stars signs of Roman gods imaginary region that encompass the path of the planets 6. Comets are celestial bodies moving about the solar system in elliptical orbits usually accompanied by a long shining tail hyperbolic orbit always accompanied by a shining head hyperbolic orbit without projecting any tail or head elliptical or hyperbolic orbits, usually accompanied by a shining tail 7. The strongest evidence that comets are members of our solar system comes from: [CDS 1992] their effect on the lives of man the shape and length of their tails their composition the shape of their orbits 8. If there is no Sun, the colour of the sky would be: orange blue black yellow 9. Which of the following celestial bodies bear, ‘The Sea of Tranquility’ and ‘The Ocean of Storms’ ? Mars Sun Moon Venus 10. The distance of the nearest star besides the sun from the earth is : 4.3 light years 95 x1015 m 4.2 light years 4.9 x 1111m 11. The time required by moonlight to reach the earth is : 2 sec 1 sec 1.3 sec 2.3 sec 12. The same side of the moon always faces the Earth because: [Railways 1994] Moon cannot change its position the period of rotation of the Moon is not equal to the period of rotation of the Earth Moon and the Earth have gravitational force the period of rotation of the Moon on its axis and period of revolution around’ the Earth is almost the same 13. Who of the following discovered the laws of planetary orbits? [Asstt Comm 2008] Isaac Newton Nicholas Copernicus Galileo Galilei Johanries Kepler 14. The Saturn rings were discovered by: Galileo Newton none of these Copernicus 15. The radiant energy of the sun is transmitted in the form of: short waves long waves particles none of these 16.

[NDA 2008] Revolution of Earth Rotation of Moon Revolution of Moon Rotation of Earth 18. The ‘Solar Corona’ mainly consists of: molten lava ice cosmic rays gases 19. The term ‘meteor’ is applied to an interplanetary body: after it enters the earth’s atmosphere and explodes in mid air as a ball of fire after it enters the atmosphere of the earth after it enters the earth’s atmosphere and lands on the surface of the earth without exploding in mid-air before it enters the earth’s atmosphere 20. The exact time taken by the earth for single rotation on its own axis is: [RRB 1991] 23 hrs 56 minutes 4.09 sec 24 hrs 35 sec 23 hrs 50 minutes 7.2 sec 24 hrs Loading … Share this:WhatsAppTelegramTweet Related
