#3049: Incoming Asteroid

[A log chart is shown with several labels. Above it there is header:]

An asteroid is headed straight for Earth! That's...

[A log scale of lengths is shown on the left with a label at the top with an arrow pointing to the first number from the top shown next to the scale.]

Asteroid size

[The log scale starts with only 7 smaller ticks before the first large tick, and then there are the regular 9 small ticks in log fashion between each of the ten larger ticks, and then only 8 small ticks beneath the last large tick. Each of the 10 larger tick is labeled with a length size. With the first at the top being the one with an arrow pointing at it:]

1 cm

10 cm

1 meter

10 meters

100 meters

1 km

10 km

100 km

1,000 km

10,000 km

[Around but not precisely at each labeled size there are ten descriptions of what should follow the header given such a size asteroid was about to hit Earth:]

[1 cm:] ...Good news! Meteors are pretty!

[30 cm:] ...Great news! You might see a fireball!

[3 m:] ...Ok news, unless you have expensive windows or are very unlucky.

[60 m:] ...Bad news, especially if you live near the city it's aimed at.

[600 m:]...Bad news, especially if you live on the continent it's aimed at.

[9 km:] ...Bad news for your species.

[50 km:] ...Bad news for your phylum.

[300 km:] ...Bad news for your biosphere.

[2,000 km:] ...Good news for any life that might someday evolve on Earth's new moon.

[25,000 km:] ...Bad news for whatever planet is about to get hit by Earth.
