A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km.

**Explanation:**

The correct answer is option **B) Distance**.

A light-year is a unit of distance used in astronomy to measure large distances in space. It is defined as the distance that light travels in one year in a vacuum. Since light travels at a constant speed of approximately 299,792 kilometers per second (or about 186,282 miles per second), the distance covered by light in one year is immense.

To better understand the concept of a light-year, let's break down the distance calculation and the significance of using this unit in astronomy:

**Definition of a Light-Year:**
- A light-year is the distance that light travels in one year.
- Light travels at a speed of about 299,792 kilometers per second (or about 186,282 miles per second).
- Therefore, in one year, light can travel about 9.46 trillion kilometers (or about 5.88 trillion miles).

**Importance of Light-Years in Astronomy:**
- The vast distances between celestial objects in space make it impractical to use conventional units like kilometers or miles.
- Astronomers use light-years to measure the distances between stars, galaxies, and other objects in the universe.
- Light-years allow us to comprehend the enormous scale of the universe and the time it takes for light to travel across such vast distances.

**Examples of Light-Years:**
- The nearest star to Earth, Proxima Centauri, is approximately 4.24 light-years away.
- The Andromeda Galaxy, our closest neighboring galaxy, is about 2.537 million light-years away.
- The observable universe is estimated to be about 93 billion light-years in diameter.

In conclusion, a light-year is a unit of distance used in astronomy to measure the vast distances between celestial objects. It represents the distance that light travels in one year and is an essential tool for understanding the scale and size of the universe.

Similar CLAT Doubts

Direction: Read the passage and answer the questions given below.Solar power tariffs keep crashing, without an end in sight. That is good news. Media reports indicate that recent bids invited by Solar Energy Corporation of India (SECI) recorded tariffs of Rs 2 per unit, a marked fall from the previous low of Rs 2.362.36 per unit. The constant lowering of tariffs gels with India's ambitious plan to transition towards, increasing the incidence of renewable energy sources to power the economy. Under the umbrella of renewable energy sources, solar power is arguably the most important. It is where technological advances promise to make today's low tariffs irrelevant soon.The Narendra Modi government signalled that increasing solar power generation is a policy priority early in its first term. It set a target of increasing installed capacity to100 GW by 2022. It was a smart move which coincided with a crash in prices of solar energy equipment. To illustrate, India's solar capacity at the end of 2019-20 was 34.62 GW, of which 65% had come up in the preceding three years. The favourable global environment was supplemented by some sensible policy decisions to encourage investment in solar power.Policies such as waiving interstate transmission charges and setting up solar parks to reduce capital costs played a part in the boom. To build on this and hasten India's transition to an energy economy less dependent on fossil fuels, we need to address challenges that lie ahead. China has played an important part in the ramp up of solar capacity as it is a large supplier of solar cells. In the last four years, China has supplied around 75% to 90% of the value of solar cells imported into India each year. For strategic reasons, the situation cannot continue.Q. What is implicit from these lines of the passage"In the last four years, China has supplied around 75% to 90% of the value of solar cells imported into India each year".
