As of October 2023, numerous artificial satellites have been launched over the past five years, including those from various countries and private companies. Notable launches include SpaceX's Starlink satellites for global internet coverage, NASA's Artemis missions, and various Earth observation satellites like Planet Labs' Doves. To get a comprehensive list, one can refer to databases such as CelesTrak or the UN Office for Outer Space Affairs, which track satellite launches and missions.
As of October 2021, the most recent satellite sent into space is likely to be the one launched within the last month or so. Satellites are frequently launched into space for various purposes, so it is best to check the latest news to find the exact date of the last satellite launch.
Satellites can last anywhere from a few years to several decades in space, depending on their design, intended mission, and how well they are maintained. Factors such as exposure to radiation, micrometeoroids, and orbital decay can affect the lifespan of a satellite. Some satellites are designed to be replaced or de-orbited after a certain period of time.
Some satellites last longer then others. The age can be determined by the efficiency of the machinery that it works with. Example: One of the satellite's solar panels have been damaged by debris. That satellite will not last as long as one that has its solar panels at full efficiency.

The typical lifespan of a satellite is around 5-15 years, depending on factors like its design, construction, and operational use. However, some satellites have been known to exceed their planned lifespans and continue operating for several decades.
Uranus had 27 known moons last time I checked. There are no artificial satellites.
If you taking care of the GPS, It will last about 5 years
As far as I know, it can last for 5 years.
The last space probe launched was the Tianwen-1 mission to Mars, which launched in July 2020 by the China National Space Administration.
an artificial hearts can last from about 5 months to about 5 years
It lasts for a period of few months to a period of 20 years.

Artificial turf is a long-lasting and practical solution for backyard spaces, especially in desert environments where natural grass struggles to survive. On average, high-quality artificial turf lasts between 15 and 20 years in a residential backyard when properly installed and maintained. At The Turf Shed (theturfsheddotcomdotau), modern turf products are designed to withstand intense sunlight, high temperatures, and daily use without losing their lush appearance. In desert climates, advanced UV-stabilized fibers help prevent fading and brittleness caused by constant sun exposure. Quality turf also features durable backing and strong stitching, allowing it to handle foot traffic, pets, and outdoor furniture. While artificial grass does not require watering, mowing, or fertilizing, simple care—such as rinsing off dust, brushing fibers upright, and removing debris—can significantly extend its lifespan. For homeowners who miss the vibrant green lawns of childhood, artificial turf offers a consistent, year-round solution. Even in harsh desert conditions, it stays green, soft, and inviting without the high water costs of natural grass. With the right product and professional installation, artificial turf can bring back that nostalgic green look while remaining cost-effective and environmentally responsible for many years to come.

The first man-made satellite was Sputnik, launched into orbit in 1957 by the Soviet Union. The first American satellite was Explorer, launched the following year. The oldest satellite still in orbit is Vanguard, launched in 1958 by the US. There are now thousands of satellites currently in orbit, including communications satellites, GPS satellites, and the International Space Station. if you would like to see a real-time 3-D plot of satellites now in orbit, check out the JTRACK 3D web site from NASA.
Planets are not launched.
Directly, hardly at all. Most rocket fuel exhaust is water vapor, sometimes with soot mixed in, but there haven't been all THAT many rockets launched in the last 50 years. And the upsides have been significant; weather satellites, communications satellites, and photo-reconnaissance satellites have all had substantial positive impacts. The upswing in teleconferencing alone has the potential to greatly reduce business air travel, to mention only one aspect, as businessmen realize that you don't have to actually GO to a place to do WORK there.
