A planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with its planetary system, which includes Earth, is known as the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems.As of 1 June 2019, there are 4,071 confirmed planets in 3,043 systems, with 659 systems having more than one planet. Belgium, is a country in Western Europe, bordered by the Netherlands, Germany, Luxembourg, France and North Sea. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi and Liège.The sovereign state is a federal constitutional monarchy with a parliamentary system. Historically, Belgium was part of an area known as the Low Countries, a somewhat larger region than the current Benelux group of states that also included parts of northern France and western Germany. In the past few centuries, Belgium served as the battleground between many European powers, earning the moniker the "Battlefield of Europe", a reputation strengthened by both world wars. The country emerged in 1830 following the Belgian Revolution when it seceded from the Netherlands. Determined not to teach by precept alone, 256 researchers on environmental issues from all Belgian universities announced on Monday that they have decided to lead by example and change their habits for the planet’s sake. Under the slogan #WeChangeForLife, the researchers have put their efforts and testimonies together on an Internet site to form a source of inspiration accessible to all and to draw the attention of political decision-makers.“To change the world, you have to begin by changing yourself,” is the message they have sent out to the public, as experts but also as citizens “like everyone else”. Their aim? To show that everyone can be an actor of the ecological transition through simple daily gestures. “A first solution accessible to all and good for the pocket is to consume less and better,” the researchers suggest. Cathy Macharis, a professor in sustainable mobility at the VrijeUniversiteit Brussel (VUB), said she issued a challenge to herself last year: to buy no new clothes or shoes for a year.The textile and fashion industries require, in fact, huge amounts of water and they also have an enormous environmental impact in terms of producing greenhouse gases and waste, according to various reports published in recent years.A second solution, the environmentalists say, is to eat less meat. “In Wallonia, less than 10% of the cereals produced on our lands is destined to be eaten by humans, whereas almost 50% is used to feed the animals we feed on,” they point out. Transport, isolation, renewable energy, waste management and awareness building are also among the issues raised in the testimonies that can be read on the site. The contributors, experts in climatology, geology, law, psychology and history, also described the difficulties that beset their efforts, “some of which will be resolved only by political decisions taken at the level of our society.” An exoplanet planet is a planet outside the Solar System. The first evidence of an exoplanet was noted in 1917, but was not recognized as such. The first scientific detection of an exoplanet was in 1988; it was confirmed to be an exoplanet in 2012. The first confirmed detection occurred in 1992. There are many methods of detecting exoplanets. In several cases, multiple planets have been observed around a star. Assuming there are 200 billion stars in the Milky Way, it can be hypothesized that there are 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if planets orbiting the numerous red dwarfs are included.
