Interstellar Comet 3I/ATLAS made its closest approach to Earth today.
It was approximately 170 million miles (274km) away
...so almost twice the distance to the sun.
When it was discovered in Jupiter's orbit, the interstellar comet
was moving at about 137,000 mph (221,000 kph).
Since then, 3I/ATLAS has continued to move along its predicted (hyperbolic) path.
Under the influence of the Sun's gravity, its speed, as expected, increased,
reaching 153,000 mph (246,000 kph) at perihelion – its closest approach to the Sun.
Now, as it moves away from the Sun, the comet's speed, as expected,
is decreasing as it continues to be affected by the Sun's gravitational pull.
When the comet leaves the Solar System, it will be moving at the same speed as it entered.
There's a few facts.
Not to be confused with any bullshit from Avi Loeb or other self-interested actors.
The actual science is fascinating enough.
