For starters, not only is Pluto smaller than any other planet in the solar system, but it’s also smaller than Earth’s moon.
These qualities have challenged the scientific view of Pluto’s status as a planet for years.
With Eris and other trans-Neptunian objects sharing similar characteristics with Pluto, the definition for dwarf planets was created, and Pluto got downgraded in 2006.
Where Could Aliens Be Hiding Technology in Our Solar System? | Mind Matters
Technosignatures are evidence of the activity of intelligent agents, as opposed to events or materials that the laws of nature alone can explain. They might include "radio signals, city lights, atmospheric changes like CO2, and free-floating spacecraft."
Or, reaching back into the past, they might be engravings on bone from 51,000 years ago or a child's burial from 80,000 years ago. Technosignatures are events and entities that nature did not simply generate without some form of thought as a necessary ingredient.

The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system.
Two recent papers involving scientists from the University of California, Davis, use data from meteorites derived from Vesta to resolve the "missing mantle problem" and push back our knowledge of the solar system to just a couple of million years after it began to form.
NASA's asteroid spacecraft Lucy launches this week on ambitious 12-year mission | Space
NASA's next asteroid-bound mission to explore the earliest days of our solar system is nearly ready to launch.
The Lucy spacecraft is targeting a launch window that opens on Saturday (Oct. 16). After blastoff, the spacecraft will make a 12-year journey to the outer solar system, where it will visit half a dozen ancient "Trojan" asteroids that orbit in the same path as the planet Jupiter .
Strange solar system object is part-asteroid, part-comet - California News Times
Scientists have identified unusual solar system objects with both asteroid and comet characteristics.
This object, called the 2005 QN173, is orbiting like any other object. asteroid However, most of such objects are rocks that do not change much when looping through the solar system. According to a new study, the 2005 QN173 (hence the name), first discovered in 2005, is not.
Mercury Space Mission Offers Rare Glimpse Of Least Explored Planet In Solar System
Mercury, the least-explored planet in our solar system was recently captured by BepiColombo, a joint mission between European Union and Japan . In this image of Mercury, one can see the craters on the planet's surface, which are akin to the craters on Earth's Moon.
BepiColombo, jointly administered by the European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) flew by Mercury earlier this week. The mission was launched in 2018 from Spaceport in Europe .
