Can you interpret this table after clicking "generate ephemeris"? Apologies, wrong start date. Here is a better date

2023-Jan-27 00:00 05 36 25.46 -15 49 26.7 11.257 n.a. 0.00009763564414 -4.5253559 124.0871 /T 55.9081 5361.0333 220.58166 -35.57426 n.a. n.a.

Is that bolded underlined (me) number on January 27 a distance?
 Quoting: Lago


"Our society relies on more than 800 satellites operating in the radiation belts for communication and navigation. The outer radiation belt is typically about 8,400 to 36,000 miles above Earth's surface. The most intense area of radiation within the outer belt is between about 9,000-12,000 miles above Earth's"

The next question would be how long does it fly through the satellite belt?

0.00032 = about 30,000 miles

2023-Jan-27 02:54 17 22 56.09 +19 38 34.5 16.603 n.a. 0.00032274688621

0.00006 AU (1 AU is the distance between the earth and sun) = about 5000 miles

2023-Jan-27 00:28 00 34 17.24 -51 20 42.1 14. n.a. 0.00006671102255

over 2 hours! Actually its double that time-close to 5 hours! (flying in and out) How fast is it traveling? Can anybody help?


I found this snippet:

"Asteroids zip through space at astonishing velocities. The speed at which asteroids move depends on their distance to the Sun. The closer they are, the greater the speed. That said, even Earth-crossing asteroids, or NEOs, travel around 25 kilometers per second — yep, per second!"

OK 4 hours = 360,000 miles That's quite a time and distance to hit a satellite.

This is an actual picture of the asteroid taken Jan 24..stunning in that someone found it!
