A moon is a natural satellite rotating around a planet. While moons vary in size, each moon is much smaller than its planet. There are 176 known natural moons orbiting planets in our Solar System. 168 moons orbit the “full-size” planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), while 8 moons orbit the smaller planets calling dwarf planets (Ceres, Pluto, Haumea, Makemake, and Eris). Several moons in our solar system are larger than the planet Pluto and two moons are larger than the planet Mercury. Many people think that the answer to ‘what is the largest moon in the Solar System’ is our Moon. It is not. Our Moon is the fifth largest Moon in the solar system. Let’s explore the moons of the solar system. The below is the top 5 largest moons in the solar system. This is a partial list of Solar System objects by size, arranged in descending order of mean volumetric radius, and divided into several size classes. These lists can also be sorted according to an obje

The moon is a solid natural object that orbits around a planet. It is a planet’s natural satellite. No definite scientific explanation has satisfactorily answered the question of how moons came into existence, although there are several theories. The Earth’s Moon was thought to be the only moon but after the invention of the telescope, other moons on other planets were discovered. Each planet has one or more moons except Mercury and Venus and the dwarf planet Ceres. Jupiter has 79 moons the highest number in the solar system. Technological advancements have made it possible for man to discover and even go on expeditions to the moon. Jupiter’s Ganymede is the largest moon in our solar system. Ganymede is a satellite of Jupiter (Jupiter III), is the largest and most massive of the  Solar System’s moons. The ninth largest object in the Solar System, it is the largest without a substantial atmosphere. It has a diameter of 5,268 km (3,273 mi) and is 8% larger than the planet Mercury, alth

Many people may not think that how can littering affect animals, as humans consume natural resources, they, too, create byproducts that enter Earth’s varied ecosystems. Plastic waste, water pollution, soil runoff, and jars and bottles make up just a few of the human-made products and byproducts that can harm the Earth and the species that live on it. The damage can be physical — six-pack rings strangling marine life — or chemical — fertilizers causing algal blooms — but in either case, they can cause lasting damage to the flora and fauna of an area. On average we receive 14 calls a day about animals affected by litter and these calls spike in the summer months. And, as pet owners go directly to vets, and many injured wild animals are never found, it’s estimated that the actual figure of animals injured by litter is much higher than we currently know. Plastic Waste Discarding plastic products, including grocery sacks, rapidly fills up landfills and often clog drains. When plasti

Many people may not think that how does littering affect the Earth. In reality, littering has an extremely negative impact on the earth. Littering tends to damage areas where we live, work and where children play. There are different factors that lead to littering. Some factors relate to what people do, while others come from areas of manufacturing. Litter consists of trash and household toxic substances that are improperly disposed of on land or in water. Whether the litter is intentional or unintentional, large or small, it can drastically affect the earth for years to come. Before carelessly tossing another item out the window or looking the other way when someone else does, consider the impact you can make on the earth by recycling, reusing and disposing of waste properly. Litter can come in many different ways and mainly because people can sometimes be rather careless and negligent. Who does it?  Well, a lot of times we see someone driving ahead of us, toss an empty to-go cup

Over the past year, young people around the world have united in the fight to change the system and combat climate change. Sixteen-year-old Swedish Child Environmental activist Greta Thunberg is arguably the most well-known figure in the climate action movement, but she is not alone. Along with Greta is a host of young activists around the world, fighting for the planet, and demanding that people in positions of power stop chasing money and actually combat the burning issue. Greta Tintin Eleonora Ernman Thunberg; born 3 January 2003 is a Swedish environmental activist on climate change whose campaigning has gained international recognition. Thunberg is known for her straightforward speaking manner,  both in public and to political leaders and assemblies, in which she urges immediate action to address the  climate crisis . Thunberg’s activism started after convincing her parents to adopt several lifestyle choices to reduce their own carbon footprint. In August 2018, at age 15, she st

If you’ve never thought about your carbon footprint while traveling, it’s time to start. Adopting even one of these eco-friendly suggestions can make a big difference for our planet—and future generations. The negative rightway environmental impact of many large cruise ships is well documented. Each day, they can generate emissions equivalent to 12,000 cars . But some cruise lines are focused on making improvements. For example,  Windstar Cruises’  three sailing ships are able to power themselves with wind in their billowing sails when the conditions are right (and switch to engine power as needed), which allows the vessels to reduce fuel usage while providing a more scenic and memorable cruise experience for guests. Coming at sustainability from a different angle,  Royal Caribbean ‘s family of brands (including Celebrity Cruises and Azamara) now offers 1,400 sustainable shore excursions through tour operators who are GSTC-certified.

Polar bears, yaks, mountain goats, snowy owls, and arctic foxes are just a few of the unique animals that live in the tundra biome. In physical geography, tundra is a type of biome  where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian from the Kildin Sámi word meaning “uplands”, “treeless mountain tract”. Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The  ecotone  (or ecological boundary region) between the tundra and the forest is known as the  tree line  or timberline. The tundra soil is rich in nitrogen and phosphorus. The tundra is one of the harshest biomes and it is definitely the coldest! Temperatures in the tundra can reach as low as minus 25 degrees Fahrenheit! Beneath the tundra is permafrost. Permafrost is a permanently frozen sublayer of soil. There is very little rain or snow in the tundra, usually less than 15 inches

Plants growing in the tundra are specially adapted to cold and windy environments. Special adaptations of plants growing in the tundra, Plants need warmth and sunlight to grow and reproduce. In the Arctic tundra, warmth and sunlight are in short supply, even in the summer. The ground is frequently covered with snow until June, and the Sun is always low in the sky. Only plants with shallow root systems grow in the Arctic tundra because the permafrost prevents plants from sending their roots down past the active layer of soil. The active layer of soil is free from ice for only 50 to 90 days. Arctic plants have a very short growing season. However, in spite of the severe conditions and the short growing season, there are approximately 1,700 kinds of plants that live in the Arctic tundra. Some of the plants that live in the Arctic tundra include mosses, lichens, low-growing shrubs, and grasses–but no trees. In fact, “tundra” is a Finnish words which means “treeless”.

The whale shark is the largest species of fish living in the world today. Fish vary greatly in size. The whale shark and basking shark exceed all other fish by a considerable margin in weight and length. Fish are a  paraphyletic  group that describes aquatic vertebrates while excluding tetrapods, and the bony fish that often represent the group are more closely related to  cetaceans  such as whales, than to the cartilaginous fish such as sharks and rays. 10. Reef manta ray The Manta alfredi is the second biggest species of ray and the tenth biggest fish species living in the world today. The fish is generally found in the tropical and subtropical marine waters but are absent in the East Pacific and the West Atlantic. The fish can weigh as much as 1.4 tons and attain lengths of up to 5.5 m. It primarily consumes zooplankton and is a filter-feeder. Although it is rarely predated upon due to its considerable size and high speed, human activities like overfishing have adversely
