Q-1) The number of staellites of the planet is Mercury is
(a)
(b)
(c)
(d)
The nearness of Mercury to the massive gravity influence of the Sun is the likely reason that no natural satellites are present, although it is possible that one or more may have existed in the past.
Q-2) The Planet Mercury is revolving around the Sun in an elliptical orbit, as shown in the given figure. The Kinetic energy of Mercury is greatest at the point labelled
(a)
(b)
(c)
(d)
Q-3) The number of zodiacs is
(a)
(b)
(c)
(d)
In both astrology and historical astronomy, the zodiac is a circle of twelve 30° divisions of celestial longitude that are centered upon the ecliptic: the apparent path of the Sun across the celestial sphere over the course of the year.
Historically, these twelve divisions are called signs.

Q-8) Which amidst the following planets has its orbit closest to Sun ?
(a)
(b)
(c)
(d)
Venus is the brightest planet in our sky and can sometimes be seen with the naked eye if we know where to look. It is the solar system’s brightest planet — yellow clouds of sulfuric acid reflect the sun’s light brightly and has its orbit closest to sun but only next to mercury.
Q-9) Which one of the following planets has no moon?
(a)
(b)
(c)
(d)
Mercury and Venus are the only two recognized planets in our solar system without moons.
However, there are many, many planets in the universe and a significant portion of these, if our solar system is assumed representative of at least a significant portion of the universe’s planetary systems likely have no moons.

(a)
(b)
(c)
(d)
Q-11) Which of the following stars is known as Fossil star?
(a)
(b)
(c)
(d)
White Dwarf is known as Fossil star. They are supported by electron degeneracy pressure. It amplifies the contrast with red giants.
They are both very hot and very small. They are the opposite of black holes. They are the end-products of small, low-mass stars.
Q-12) How much of the total surface area of the moon is never visible from the earth

(a)
(b)
(c)
(d)
The group of stars arranged in a definite pattern is called a constellation. In modern astronomy, a constellation is an internationally defined area of the celestial sphere.
These areas are grouped around asterisms, which are patterns formed by prominent stars within apparent proximity to one another on Earth’s night sky.
Q-15) In a solar or lunar eclipse, the region of the earth’s shadow is divided into
(a)
(b)
(c)
(d)
An eclipse occurs when a star (such as Sun) aligns with two celestial bodies, such as a planet and a moon. The closer body casts a shadow that intersects the more distant body. This means that “things get dark.”
The region of the shadow is divided into an umbra, where the light from the star is completely blocked, and a penumbra, where only a portion of the light is blocked.
Beyond the end of the umbra is a region called the antumbra. For an observer inside the antumbra of a solar eclipse, for example, the moon appears smaller than the sun, resulting in an annular eclipse.
Q-16) Seasonal changes is caused by which one of special characteristic of Earth’s motion?
(a)
(b)
(c)
(d)
Q-17) On the surface of the moon, the
(a)
(b)
(c)
(d)
Q-18) Satellite having the same orbital period as the period of rotation of the Earth about its orwn axis is known as
(a)
(b)
(c)
(d)
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometres (22,300 miles) directly over the equatorand revolves in the same direction as the earth rotates (west to east).
Q-19) The different phases of the moon are caused by
(a)
(b)
(c)
(d)
The different phases of the moon are caused by changing the angle of the earth with respect to moon. The moon’s phases are a result of the moon’s orbit around the earth as it reflects the sun’s light.
The lunar phases vary cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon, and Sun.
