Light from the Sun takes 8 minutes and 20 seconds to reach Earth

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

Human DNA length: 2 meters, Sun-Earth distance: 150 million km, repetitions: 900,000,000

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

Venus's rotation period exceeds its orbital period, resulting in a longer solar day than year

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

The observable universe is about 93 billion light-years in diameter

The observable universe spans approximately 93 billion light-years across
