A day on Venus is longer than its year — it rotates so slowly it takes 243 Earth days

If the gravitational constant were twice as large as its current value, how would the orbital period of Earth around the Sun change?

Orbital period would halve due to inverse square law relationship

Sunlight travels approximately 149.6 million kilometers to Earth in 8 minutes and 20 seconds

How long does it take for radio waves from the Voyager 1 spacecraft, launched in 1977, to reach Earth, given the current distance between the two?

Voyager 1's radio waves take approximately 17 hours to reach Earth, considering its current distance of about 145.3 astronomical units

Your DNA stretched end to end would reach the Sun and back over 600 times

Why GPS satellites must correct for both special and general relativistic effects — or positions drift by 10 km/day

GPS satellites account for relativistic effects to ensure precise positioning, averting a daily drift of approximately 10 km
