It was first spotted back in March of 2022 at the Zwicky Transient Facility (hence the ZTF in its name) in California. At first, they thought it could be an asteroid, but, one night later, a Japanese observer saw a surrounding coma, making it a comet.
It made its closest approach to Earth early Wednesday morning, about 26 million miles away, and it is now headed quickly out of our solar system.
How, When and Where to See the Green Comet Before It Disappears From Sky
A magnificent green-colored comet , which came soaring past its closest approach to the Earth on Wednesday, will still be visible for a number of days.
On February 1, the comet (C/2022 E3 (ZTF)) passed Earth at a distance of roughly 26 million miles, and has been faintly visible to the naked eye for the last few weeks.
A green comet is passing by Earth. Here's how to see it.
Later today, a visitor from the solar system's frigid outermost regions will come within 26 million miles of Earth: a ball of ice and dust that will glow in our skies with an emerald gleam.
For the past several months, the recently discovered comet C/2022 E3 (ZTF) has been dazzling stargazers and astrophotographers, with the excitement ratcheting up in recent weeks.
Soon Every Spacecraft can Navigate the Solar System Autonomously Using Pulsars - Universe Today
If you want to know where you are in space, you'd better bring along a map. But it's a little more complicated than riding shotgun on a family road trip.
Spacecraft navigation beyond Earth orbit is usually carried out by mission control. A series of radio communication arrays across the planet, known as the Deep Space Network , allows operators to check in with space probes and update their navigational status.

The James Webb Space Telescope gets its own micrometeoroid forecast — here's how | Space
Even as the James Webb Space Telescope is allowing astronomers to see inside vast, distant galaxies, it's also studying some tiny, nearby objects — albeit inadvertently.
These are micrometeoroids, tiny mysteries zipping through the solar system at lightning speed.
