It depends on where you are measuring it from. Its distance from the earth varies depending of the relative positions in their orbit, but all planets in our solar system are considerably less than 1 light year distant.
Rigel is approximately 860 light years away from Earth.
The average distance between Mercury and Venus is approximately 0.5 astronomical units (AU), where 1 AU is approximately 93 million miles. One light year is about 63,241 AU, so the distance between Mercury and Venus is about 0.0000079 light years.
Mintaka (δ Orionis, 34 Orionis) is a star some 900 light years distant in the constellation Orion.

The famously first-observed black hole in Cygnus known as Cygnus X-1 is about 6,070 light years distant.
Because the speed of light is finite (around 186,000 miles per second) and the stars are so distant, it takes a long time for the light to reach the telescope from the stars - at least 4.2 years. Many objects are millions of light years distant, meaning that what we see in the sky is from the distant past.
You are confused. "Light-year" is a measurement of DISTANCE, the distance that light travels in one year; it is not a time period. Venus is, depending on where Venus and Earth are in our respective orbits, between 2 and 14 light-minutes away; light would take somewhere between 2 and 14 minutes to span the distance. You can convert easily minutes into years; there are 60 minutes in an hour, 24 hours in a day, and 365.26 days in a year.
Depending on the orbits of Venus and the Earth around the Sun, the distances between Venus and Earth vary. It as been as close as 38.2 million km, but average distance of 41 million km. 41 million km is approximately 0.000004333703419500923 Light Years

A telescope can cover distances of thousands or even millions of light-years, depending on its size and capabilities. Telescopes can observe objects in the far reaches of the universe, allowing us to study celestial bodies that are incredibly distant from Earth.
If it has been 13 billion years since fusion reactions first ignited in the sun to produce visible light,then that light has traveled 13 billion light years distant from where the sun was at that time.Whether it's intense enough to be detected at that distance is another question. But that's where thephotons have migrated to.
Many extra-solar planets have been detected, some many light years distant, at our present stage of technology it would take many millions of years to reach them
