Asteroid 2020 DB5 has no relation to the James Bond car the Aston Martin DB5, but this 850-meter asteroid is set to pass Earth soon, according to NASA.

    I came here to complain about the measurement too, so I’m converting it.
    The Asteroid is 850m across, which is about 28 blue whales long, or 283 bottlenose dolphins, or 1118 golden retrievers.

      Not to worry, here’s gpt’s answer:

      To begin with, we need to know the average volume of a narwhal. According to the National Oceanic and Atmospheric Administration (NOAA), the average length of a male narwhal is about 16 feet (4.9 meters) and its weight is about 1,800 kg. The volume of a narwhal can be calculated by using the formula for the volume of a cylinder, where the radius is half of the length.

      Volume of a cylinder = π × r^2 × h

      Radius = length/2 = 4.9/2 = 2.45 meters

      Height = 16 feet ≈ 4.9 meters

      Volume of a narwhal = π × 2.45^2 × 4.9 ≈ 96.3 cubic meters

      Next, we can estimate the volume of a banana. The volume of a banana may vary depending on its size and shape. For simplicity, let’s assume that a medium-sized banana has a volume of 100 cubic centimeters (cc) or 0.1 liters.

      Now, we can divide the volume of a narwhal by the volume of a banana to get an estimate of the number of bananas needed to fill the narwhal’s volume.

      Number of bananas = Volume of narwhal / Volume of banana

      Number of bananas ≈ 96,300,000 cc / 100 cc = 963,000 bananas

      Therefore, it would take around 963,000 bananas to fill the volume of one narwhal, although this estimate may not be very accurate due to the assumptions and approximations made.

      I was too lazy to do this manually, so I punched it into GPT 4. I did verify that the math, indeed, checks out.

      Edit: Sorry for the edits. GPT assumed the tusk in the calculation, so I had to ask it to remove the tusk for this math to check out properly.

      1. The size of a narwhal: Narwhals typically range in size, but males on average can be about 4.7 meters long.
      2. The length of a banana: The length of a banana varies, but a typical banana is about 18 centimeters long.

      Let’s start by converting the asteroid size from narwhals to meters.

      If 99 narwhals equal 850 meters, then one narwhal would be approximately 850/99 ≈ 8.59 meters.

      Now, this doesn’t match the usual size of a narwhal that we have (4.7 meters). There might be a discrepancy in the calculation, but for the sake of this exercise, let’s use the size provided.

      Now, let’s convert the asteroid size to bananas.

      850 meters is equivalent to 850 * 100 = 85000 centimeters.

      If 1 banana is 18 cm, then:
      85000 cm / 18 cm/banana ≈ 4722.22 bananas.

      So, the asteroid is approximately 4722 bananas long, if we base the calculation on the given size of the narwhal. But please note, this is a fun approximation and might not be precise.

    99 narwhals? How many football fields is that? And bananas? If we stop using standard units I’m lost xD

    Size is a terrible word to use. Something with a length of 99 narwhals is far bigger than one with the mass of 99 narwhals.

    And this is how today I learnt that the Brooklyn Bridge is the size of 99 narwhals: https://usatoday.com/story/news/nation/2023/06/13/nasa-asteroid-brooklyn-bridge-passing-earth/70316864007/

    And an orca is the size of 1.18 narwhals: https://www.jpost.com/science/article-745973

    And, finally, an alpaca is the size of 5.6 orcas or 6.6 narwhals: https://www.msn.com/en-us/news/technology/asteroid-the-size-of-15-alpacas-to-fly-past-earth-on-monday-nasa/ar-AA1cHfy5

    I’m not a New Yorker, but it looks to me like the Brooklyn Bridge should be able to fit more than 15 alpacas.
