Question

Halley's comet is a comet that passes close to Earth every 75 years. Based on this passage, which gravitational attraction has the most influence on the movement of this astronomical object?
A. Attraction between the comet and Jupiter
B. Attraction between the comet and the Moon
C. Attraction between the comet and Earth
D. Attraction between the comet and the Sun

Answer 1

D. Attraction between the comet and the Sun

Explanation:

• The 6th paragraph in the passage describes that the Sun has the strongest gravitational force.

• "Gravity is the invisible force that attracts all objects, no matter their size or mass.  The Sun has the strongest gravitational force of any object in the solar system, attracting all astronomical objects into orbit around itself.  Without this force, everything would fly off in all directions through the universe."
• Based on this passage, the attraction between the comet and the Sun has the most influence on the movement of the Halley's comet

Answer 2

The gravitational attraction between the comet and the Sun is the most influential.

The sun has the strongest gravitational force with acceleration due to gravity of 274 m/s².

The sun has the most influence on the movement of this astronomical object due to its strong gravitational pull.

The force of attraction between two mass on the universe can be determined using Newton's universal gravitational law;

$F = \frac{GM_1 m_2}{r^2}$

where;

m is the mass of the objects

r is the distance between the objects

Thus, we can conclude that the gravitational attraction between the comet and the Sun is the most influential.
