Question

these three images show observations of halleys comet, which was visible from earth in the years 1835, 1910, and 1986. in what year do you predict that halleys comet will again be visible from earth? a. 2061 b. 2086 c. 2035

Explanation:

Step1: Calculate the time interval between 1835 and 1910

$1910 - 1835=75$

Step2: Calculate the time interval between 1910 and 1986

$1986 - 1910 = 76$
Since the intervals are approximately 75 - 76 years. Taking an average of these intervals (approx 76 years).

Step3: Predict the next year

Add 76 years to 1986: $1986+76 = 2062$. The closest option is 2061 (there could be slight variations in actual orbital calculations).

Answer:

A. 2061
