Assume that the Moon is hit by about 25 million micrometeorite impacts each day (this number comes from observations of meteors

mestny [16]

Answer:

3.03 Billion Days or 8.30 Million years

Explanation:

Given,

No. of micrometeorite impacts per day on the Lunar surface = 25000000

Impacts needed to erase a footprint = 20

Area of footprint = 300 cm²

We know that surface area of the Moon = 37.93 Million Km² = $37.93\times 10^{16} cm^{2}$

To find: How long will it take to erase one footprint?

Using the above information,

No. of impacts per cm² per day is

$= \frac{25000000}{37.93\times 10^{16}}$

No. of impacts on area of a foot print (300 cm²) per day will be,

$= \frac{25000000}{37.93\times 10^{16}}\times 300$

$= 6.59\times 10^{-9}$

To erase the footprint there must be 20 impacts on the area of footprint.

Time taken for $6.59\times 10^{-9}$ impacts = 1 Day

Time taken for 1 impact is

$= \frac{1}{6.59\times 10^{-9}} days$

Hence, time taken for 20 impacts will be

$= \frac{1\times20}{6.59\times 10^{-9}} days$

$= 3.03 \times 10^{9} days$

$= \frac{3.03 \times 10^{9}}{365}years$

$= 8.30 \times 10^{6} years$

It would take around 3.03 Billion Days or 8.30 Million years for one of the footprints left by the Apollo astronauts to be erased.
