B
Correct answer
Explanation
The Sun contains approximately 99.8% of the total mass of the entire Solar System. This is because the Sun's mass is about 1.989 × 10^30 kg, while all the planets, asteroids, comets, and other objects combined make up only about 0.2% of the Solar System's mass. Jupiter, the largest planet, itself contains about 71% of all planetary mass, but even Jupiter is tiny compared to the Sun.

Sun Spots
-
Diamond ring
-
Mega land
A
Correct answer
Explanation
Baily's beads are the points of sunlight that shine through the valleys and craters on the moon's surface just before and after totality during a solar eclipse. They appear as bright beads or pearls of light around the dark moon. The diamond ring effect is related but different - it's the single bright spot that appears just as totality ends.

-
8 minutes & 3 seconds.
D
Correct answer
Explanation
Light travels from the Sun to Earth in approximately 8 minutes and 20 seconds (actually 8 minutes 20 seconds on average, not exactly 3 seconds). The exact time varies slightly depending on Earth's position in its orbit, ranging from about 8 minutes 10 seconds to 8 minutes 24 seconds. Among the given options, 8 minutes 3 seconds is closest to the actual value.

7.5 mins
-
7.3 mins
-
8.0 mins
B
Correct answer
Explanation
A total solar eclipse occurs when the Moon completely covers the Sun. The maximum possible duration at the equator is approximately 7.5 minutes due to the Moon's orbital speed and angular size relative to the Sun. Longer durations would require the Moon to be closer or moving slower than physics permits.
A
Correct answer
Explanation
A total solar eclipse causes very subtle changes in daylight until the Sun is almost completely covered. Only when more than 90% of the Sun is obscured does the dimming become noticeable to the human eye.

8 per year
-
6 per year
-
9 per year
-
5 per year
D
Correct answer
Explanation
The maximum number of solar eclipses (including partial, annular, and total) possible in one year is 5. This occurs due to the alignment of the Sun, Moon, and Earth at the lunar nodes during eclipse seasons.
A
Correct answer
Explanation
There must be at least 2 solar eclipses per year somewhere on Earth. This minimum occurs because eclipse seasons happen approximately every 6 months when the Sun is near the lunar nodes, guaranteeing at least one eclipse per season.
A
Correct answer
Explanation
Partial solar eclipses can be observed over a very large area, extending up to 3,000 miles from the narrow path of totality. This is because the Moon's penumbral shadow covers a much broader region than the umbral shadow that creates totality.

-
1.5 years
-
3 years
-
2.4 years
B
Correct answer
Explanation
Total solar eclipses occur approximately every 18 months (1.5 years) on average. This is because the Moon's shadow is very narrow and requires precise alignment, making any given location much less likely to experience totality frequently.
