It will appear first at 10 degrees above the horizon before moving right across the sky for four minutes.
Starlink satellite actual size. And as for latency. Starlink s size dimensions are difficult to find. Starlink is a satellite constellation being constructed by spacex to provide satellite internet access. The constellation will consist of thousands of mass produced small satellites in low earth orbit leo working in combination with ground transceivers spacex also plans to sell some of the satellites for military scientific or exploratory purposes.
With satellite internet that means your signal has to travel 22 200 miles to reach the satellite then back down to the website server back up to the satellite and back to you. Assuming spacex aims to launch one dedicated 60 satellite starlink mission every 6 8 weeks the company could easily have a constellation of more than 600 satellites in orbit by the end of 2020. The faq says that the body is 2 8 m x 1 4 m estimated and that the solar panel array is 2 8 m x 10 m estimated. First starlink 6 7 will appear moving from west to southeast at 8 58pm.
That distance creates real world ping times on the order of about 600 to 1200ms. Well latency is the time it takes for your internet signal to travel from your computer to your isp to the website server and then back to you. Current satellite solutions have limited bandwidth with higher ping times. The faq here on reddit is the closest i could find to actual units most sites use comparisons to doors or cars that seem wrong.
