A recent breakthrough in satellite technology promises to revolutionize how we observe the Earth by enabling global coverage in just 35 minutes. A study published in Space: Science ...

So how many satellites can we actually launch to space before it gets to be too much? Experts have been sounding alarm bells for years that Earth orbit is getting a bit too crowded.

Geosynchronous orbits are vital for communications and Earth-monitoring satellites. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A ...

Earth reaches aphelion every July, and this year it occurs on Thursday at 3:55 p.m. Eastern time. That Earth has an aphelion is a result of its orbit being elliptical, rather than circular.

For example, 469219 Kamoʻoalewa is an asteroid about 50 meters wide in an orbit with a period of 1.002 Earth years—just around 17 hours longer than Earth’s period!

Different altitudes – low Earth orbit (LEO), medium Earth orbit (MEO), geostationary Earth orbit (GEO) – provide one variable, but elliptical (stretched out) orbits can support new use cases.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

Satellites in LEO travel at speeds around 7.8 kilometres per second, which means they complete an orbit around Earth approximately every 90 minutes. As a result, the ISS orbits Earth about 16 ...

Earth" that is located about 154 light-years away and is nearly twice as big and four times as massive as our planet.

DoD is planning a multi-orbit architecture with satellites in low, medium, geostationary and highly elliptical orbits. The Space Force’s Space Development Agency is building a network of missile ...

In total, there will probably be "around as many small-body satellites as planetary moons," he added. However, other astronomers, like Gladman, are less sure about how many small-body satellites ...
