Since the 16th century, our understanding of what constitutes a planet has evolved significantly, influenced by advancements in space exploration and telescope technology. Changes in our understanding over time do not imply a lack of scientific accuracy but reflect the progression of scientific knowledge.
The concept of a planet has significantly changed since the 16th century. Back then, the term 'planet' usually referred only to visible objects that wandered across the sky, including the Sun and Moon along with the five objects now known as Mercury, Venus, Mars, Jupiter, and Saturn
In the 16th century, the Copernican model proposed that the Earth was one of these wandering objects, a radical concept for its time.
Modern advancements in science, particularly in space exploration and telescope technology, have drastically expanded and revised our understanding of planets.
The controversy around Pluto's demotion in 2006 from a planet to a 'dwarf planet' is a recent example of scientific advancement refining our definitions.
This continuous refinement of facts doesn't necessarily discredit future facts or indicate a lack of scientific accuracy. Instead, it shows how the scientific process works: as our tools and understanding improve, so too do our models and classifications.

Answer:
D
Explanation:
its in the ?
A large portion of our energy originates from consuming fossil fuels , consuming non-renewable energy sources dirties the air by putting all ash of harmful gases in it and also ozone harming substances which influence the atmosphere.
Conserving energy can anticipate things like synthetic compounds going into the air from control plants, or on the off chance that we drive less then we annihilate the air less in light of less CO2 outflows. Conserving energy additionally forestalls things like oil slicks into the sea.
Conserving energy can help with diminishing air, water, and land contamination in light of the diverse options we have for energy. We have sun powered power energy that is a sustainable source. Sun based power vitality doesn't contaminate the air that we inhale or discharge any ozone harming substances while creating power. You likewise have tidal energy that believers waves into clean, contamination free power. This shields the water from being dirtied.
Answer: Yes, we can fulfill all our electricity needs through solar energy as the solar panel can absorb solar energy at night and convert them to electrical energy and discharges both on day as well as night.
