The number of commercial airline flights per day, worldwide is around the 93,000 mark. If we halve that, to account for the rougly 50/50 split of day/night time, that leaves us with approximately 46,500 flights per night, worldwide. According to most astonomers, there are millions of foreign objects entering the atmosphere (approximately 100 tonnes worth) each with the capability to become a 'shooting star' each day. For the purpose of arguement, lets say 3 million each day. Again, if this is halved, we are left with approximate 1.5 million shooting stars worldwide each night. Therefore, the ratio of airplanes to shooting stars worldwide, during night time hours, is 46,500 to 1,500,000. Therefore, it is over 30 times as likely that you will see a shooting star than an airplane on any given night.
The morale of the story: Go outside and find a shooting star and stop wishing that airplanes are shooting stars.
The intensity ratio between two stars that differ by 8.6 magnitudes is approximately 630 times. This is because for every 1 magnitude difference, the ratio of intensities is about 2.512. Therefore, for an 8.6 magnitude difference, the ratio would be 2.512^8.6.

Titanium is the metal that has a low density and is sufficiently strong, making it ideal for use in airplanes and aerospace vehicles. It offers a high strength-to-weight ratio, making it lighter than steel but still able to withstand high stress and temperature conditions.
Airplanes use a fuel called kerosene.
If the radius of Betelgeuse varies by 60% within three years, its luminosity will also change proportionally. Since absolute magnitude is related to luminosity, the ratio of the two absolute magnitudes will be the square root of the ratio of the luminosities. So, the ratio of the two absolute magnitudes will be approximately 1.22.

-- stars -- meteors -- airplanes.
The ratio is 3:1 in the Cameroon flag.
Airplanes are man-made objects that travel at a consistent speed and altitude, making them distinguishable from shooting stars that are natural phenomena. Additionally, airplanes typically have blinking lights and follow a predictable flight path, further differentiating them from the quick, bright streaks of light produced by shooting stars.

In the sky, you can see clouds, the sun, the moon, stars, and sometimes airplanes.

Not necessarily. The aircraft with better power to weight ratio will fly fastest.
