In an imaginary planetary systam, the centrel star has the same mass as our sun, but is much brighter so that only a planet twice the distance between the Earth and sun can support life. According to bilogical evolution (including aging processes etc.) on that planet similar to ours, what would be the average life span of a 'human' on that planet in terms of its natural life ? The average life span of a human on the Earth may be taken to be 70 years.

In an imaginary planetary system, the central star has the same mass as our sun, but is brighter so that only a planet twice the distance between the earth and the sun can support life. Assuming biological evolution (inculuding aging process etc.) on that planet similar to ours, what would be the average life span of a 'human' on that planet in terms of its natural year ? The average life span of a human on the earth may be taken ot be 70 years.

  • Read the passage carefully and select the best answer to each question out of the given four alternatives. The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water - a key to life, as we know it on Earth - with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable .Goldilocks. zone of a star- neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1. How many planets in our solar system have liquid water?

    The nearest star to our solar system is 4.29 light years away. How mcuh is this distance in terms of par sec ? How mcuh parallax would this star show when viewed from two locations of the earth six months apart in its orbit around the sun?

    The planet Egabbac (in another solar system) has a radius twice that of the earth's but an average mass density which is the same as the earth. Would the weight of an object on Egabbac's surface to be the same as on the earth's greater than on the earth's or less than on the earth's ? If greater or less than on the earth's then by how much?

    The small dense stars rotate about their common centre of mass as a binary system, each with a period of 1 year. One star has mass double than that of the other, while mass of the lighter star is one-third the mass of the Sun. The distance between the two stars is r and the distance of the earth from the Sun is R , find the relation between r and R .
