The circumference of Earth at equator is around 40 thousand kilometers. So, it would take a conventional jet airliner flying at 900 km/h, approximately 44 hours (nearly two days) to circle around the earth over equator.
Now if we imagine, that the Earth was the size of other planets, how much time it would take to circle around it then. So, lets start calculating that. I got all the circumference values from https://solarsystem.nasa.gov/planets.

Mercury
| Circumference (thousand km) | Time (hours) |
|---|
| 15.3 | 17 |
Venus
| Circumference (thousand km) | Time (hours) |
|---|
| 38 | 42 |
Mars
| Circumference (thousand km) | Time (hours) |
|---|
| 21.3 | 24 |
Jupiter
| Circumference (thousand km) | Time (hours) | Time (earth days) |
|---|
| 439.3 | 488 | 20.3 |
Saturn
| Circumference (thousand km) | Time (hours) | Time (earth days) |
|---|
| 365.9 | 406.6 | 16.9 |
Uranus
| Circumference (thousand km) | Time (hours) | Time (earth days) |
|---|
| 159.4 | 177.1 | 7.4 |
Neptune
| Circumference (thousand km) | Time (hours) | Time (earth days) |
|---|
| 154.7 | 171.2 | 7.1 |
What about the Sun?
The Sun's circumference is 4370 thousand km, which means it would take around 4855 hours or around 202 days, for a jet airliner to travel around the Earth if it were the size of the Sun.
What about the Moon?
The Moon's circumference is 10.9 km, which means it would take around 12 hours for a jet airliner to travel around the Earth if it were the size of the Moon.
You many now also be wondering how many earths would fit each planet and the Sun. The following picture shows you that.

I hope you enjoyed reading this article, and I would love to read your comments.
excellent u have much more knowledge i get knowledge from here ur article im student of physics its for me good article and info...
Good to know that you liked this article :)
It's an interesting mental exercise, thanks for sharing it
it was really surprising to hear that mars is nearly half the size of the earth, in my mind mars wes almost equal for some reason Oo
It is completely crazy to think about flying with a plane for 202 days, so insane haha
