Can city lights be seen from space?
It might surprise you to know that even when viewed from space, city lights are brighter than the stars.
Can you see city lights from the moon?
It appears the answer is “no”. Apollo mission reports describe night-time lights from Earth orbit, but sightings at lunar distances are notably absent. For example, The sights in earth orbit were spectacular; even on the dark side, where thunderstorms and fires in Africa captured the crew’s attention.
How do we know the planets are distant?
They have been found through indirect means: telescopes detect an exoplanet by the effects the planet has on its parent star, like a faint dimming as it passes in front of the star, or the star’s slight wobble as the planet tugs on it. Only a handful of exoplanets have ever been observed directly.
What are distant planets?
Planets that orbit around other stars are called exoplanets. All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. So, astronomers use other ways to detect and study these distant planets.

How do you identify planets?
Bottom line: The most popular methods of discovering exoplanets are the transit method and the wobble method, also know as radial velocity. A few exoplanets have been discovered by direct imaging and microlensing.
What is the least known planet?
Mercury
Scientists have found the smallest known planet — smaller than Mercury, the smallest planet in Earth’s solar system.
What is the most distant planet in the universe?
Astronomers have discovered one of the most distant planets known, a gas giant about 13,000 light-years from Earth, called OGLE-2014-BLG-0124L. The planet was discovered using a technique called microlensing, and the help of NASA’s Spitzer Space Telescope and the Optical Gravitational Lensing Experiment, or OGLE.
